Doubts Raised About Legal Soundness of GPL2 521

svonkie writes "Two prominent IP lawyers have warned that the all-pervasive General Public License version 2 (GPLv2) is legally unsound. They claim GPLv3 and AGPLv3 are much better suited for the realities of modern open source software. 'If you go back in time to when GPLv2 was written, I don't think people were aware of just how ubiquitous this license would become and how closely scrutinized it would be,' said Mark Radcliffe, partner at the firm DLA Piper and general counsel for the Open Source Initiative (OSI). 'At that time, open source was not something as broadly used as it is now.' Radcliffe was joined by Karen Copenhaver, partner at Choate Hall & Stewart and counsel for the Linux Foundation, for a GPL web conference hosted by the license-sniffing firm Black Duck software"

    The article essentially says that the terminology used needs more rigorous definition, and needs to match more closely with the existing legal terminology. For example, their use of "derivative work" might have legal connotations that don't completely follow from the terms of the licence. It's not like they've determined there's some fundimental legal principle which brings the whole thing crashing down, as you see in EULAs for example.

      It's not like they've determined there's some fundimental legal principle which brings the whole thing crashing down, as you see in EULAs for example.

      Right. Which strikes me as interesting that they'd suggest "upgrading" from a distribution license (GPLv2) to a EULA (AGPLv3). Remember, if you have an in-house branch of an AGPLv3 package, and you let a customer SSH in to run it, then you have to grant them full rights to your changes (even though you haven't distributed it). I dig RMS and I love the GPL, but I hate that derivative abomination.

      • Why shouldn't they get the source code to a program they are using, even if it is over SSH? Isn't that the whole point of the Open source and the GPL. Software authors granting the same rights they enjoy to their users? When did having the program you're using running on your own computer become a prerequisite for obtaining GPL rights?

          Why shouldn't they get the source code to a program they are using, even if it is over SSH? Isn't that the whole point of the Open source and the GPL.

          The problem is that all versions of the GPL have governed distribution, and they're on solid ground with copyright law. Basically, they grant you additional distribution rights above and beyond what you'd normally be allowed as long as you comply with certain restrictions. End users don't even have to agree to the GPL to use software so licensed because usage isn't governed by copyright. The GPLv3 (and the AGPLv3, confusingly enough) even explicitly states this:

          9. Acceptance Not Required for Having Copies.

          You are not required to accept this License in order to receive or run a copy of the Program.

          Contrast with the AGPL which seeks to control how you run the software by adding:

          Notwithstanding any other provision of this License, if you modify the Program, your modified version must prominently offer all users interacting with it remotely through a computer network (if your version supports such interaction) an opportunity to receive the Corresponding Source of your version by providing access to the Corresponding Source from a network server at no charge, through some standard or customary means of facilitating copying of software.

          So, there are new limits to how I can modify the software that have never existed in any prior FSF license. If I start with a GPLv3 library and only want to use one function, then I'm allowed to do that. Not so under the AGPLv3! Taken to the extreme, imagine that Linux was relicensed under the AGPLv3. If you host a Linux server, then you have to offer copies of the Linux kernel (which holds the networking code) to any client that connects to it. Wouldn't that be fun to comply with?

          When did having the program you're using running on your own computer become a prerequisite for obtaining GPL rights?

          When the GPL was written as a distribution license.

            This is a work-around for the bug that copyright law does not define a public-performance right for software, although a similar right is defined for audio recordings, movies, and theatrical scripts.

            Thus, we had a loop-hole in that companies which performed the software over the net without ever distributing it can make substantive derivative works of the program from which they derive tremendous profit but have none of the obligations. Think of google in this context.

            I think the first FSF meeting where we discussed this was in 1994. It was seen as a significant problem even before google.

      GPL2 is not about to become invalid. But consider all of the changes we have gone through since GPL2 came out. Back then, the most complicated input device that people were likely to have in their homes was a touch-tone phone. Music came from phonograph records and cassette tape. The "@" sign was a little-used oddity on the typewriter keyboard for most people. Home computers were more the exception than the rule, and their CPUs used 16-bit addresses.

      With the advent of consumer digital media we got a ton of law, both legislative and case law. Garbage legislation like ECPA and then DMCA, and a great increase in software patenting. All of that law essentially blind-sided the GPL, which had to cope with it but was not written with knowledge of it.

      So, a license upgrade to deal with all of this is like installing a security patch on your operating system. It's just a sensible thing to do.

      The article essentially says that the terminology used needs more rigorous definition, and needs to match more closely with the existing legal terminology.

      The article also says, "This marks one of the core questions of GPLv2: Is it based on copyright or is it a contract that, while borrowing some copyright terms, ultimately stands on its own?", which is so bizzare that it makes me question the whole thing.

      I have no idea why anyone who knows anything about contract law or the GPL would ask this question. The GPL involves no consideration (payment) and therefore is not a contract in any jurisdiction governed by Common Law. The GPL further depends explicitly on the software author's copyright for its legal force.

      So why exactly would anyone think this is a "core question of GPLv2"? A core question of clueless jurnos writing far outside their comfort zone, maybe. But not a question anyone who wasn't that profoundly ignorant would ask.

          It wouldn't be the first time I have seen that definition of "extremist" or "nut" that means "a person who takes a reasonable, legally and morally justifiable action that you happen not to like." It seems to come from a line of thinking which states, "reasonable people cannot possibly disagree on something or take different positions on it; therefore, if you disagree with me, it can only be because something is wrong with you and it is now my job to label what that something is."

          Now if someone said that punching random strangers in the face for no reason should be legal and acceptable behavior, I'd say that yes, there probably IS something wrong with them. But to draw such conclusions based on the choice of software license? For code that the author didn't have to write and had no obligation to share with us in the first place? Yeah, that's a bit much.

          Besides, if you want to see an "extreme" license, read the average commercial EULA sometime. Wade through all of the legalese and look at the long list of prohibitions and restrictions. Consider whether this really benefits you as a customer and whether it was intended to. Then note that you generally don't get to review it until after you have purchased the commercial software. The freedoms that the GPL guarantees are a breath of fresh air by comparison. Maybe this is just my personal tastes, but I have always found "enjoy this, just don't restrict someone else's ability to enjoy it as you have" to be far more reasonable than "what you bought isn't really yours, and you will use it only in ways that we have decided to allow, which by the way are subject to change."

      And even then, Mr. Torvalds has stated that he prefers the spirit of GPLv2 [lkml.org] to that of GPLv3.

          Er, I think you have that backwards, but it's a common mistake, usually made by big media companies and their **AA agencies. Licensees have every right to copyright works except those rights specifically withheld by copyright law.

    This is a real issue. For instance, I wrote a physics textbook, which is open-source, and I wrote a bunch of ruby and latex code that helps to produce the pdf from the latex sources, automatically handling some things relating to placement of figures on the page that are awkward to do with plain latex. My book, including the ruby and latex code, is under CC-BY-SA. I got an email from a guy at MSU who was writing a textbook, and had already started using my code to handle the illustrations. He wanted to check whether it was okay under the license, since he didn't intend to release his own book under a CC license. Well, my answer ended up being that I really didn't know whether it was okay or not. It wasn't clear to me whether his work counted as a derived work. On the one hand, you could say that what he was using was simply some software I wrote, so his book isn't a derived work based on my software any more than a book written in MS Word is a derived work based on Word. On the other hand, there's really no perfect separation between the software and our books. When you write a book in latex, the latex code *is* a piece of software. My code generates various boilerplate in its output, some of which is text that is visible to the reader, so it's under my copyright and license. Of course I could have just told him that it wasn't an issue, and I wouldn't sue him, but I had intentionally chosen the strong copyleft because that's what I wanted. I suspect that a lawyer would tell him his work was actually not a derived work, but I also suspect that he (and his eventual publisher) wouldn't even want to get into that issue.

    Although the issue is real, it seems goofy to me to suggest GPLv3 as the fix for the problem. First off, there are huge philosophical differences between v2 and v3. Also, there is so much GPL v2 code out there that you can't necessarily just relicense under GPL v3 without causing yourself hassles with license incompatibilities. I also don't quite understand how they think they can bypass the fact that various countries have various inconsistent and ambiguous definitions of a derived work. The only thing that forces anyone to accept the GPL license attached to a work is that copyright law doesn't allow them to do certain things without a license from the author. Those things include (1) copying and redistributing the work, and (2) creating and distributing derived works from it.

      As the copyright holder, you're free to release the code to this one individual under whatever terms you want. Just because you released it once under one set of conditions doesn't mean that you're bound to release it to the MSU guy under the same conditions. Being the creator, you're free to re-license anything you want. Assuming your code isn't mixed up with someone else's, just license the Ruby code as a separate work.

        I don't understand your point. It is open source. The source code is in latex format. Latex is a Turing-complete programming language, which people use as a format for writing documents. You can download the source code of my book here [lightandmatter.com] (scroll down to the bottom of the page). The source code is under a copyleft license (CC-BY-SA). So I would say that that makes the book an open-source book by any reasonable definition of open source.

      A different license is not the answer. Neither of you knew whether his book was a derivative work under copyright law. Your license can't redefine the terms of copyright law, so no change in the wording of the CC would reduce the confusion. This is the same problem with TFA. Like the GPL, the CC licenses are grants of rights to be added to those rights we already receive under copyright law. If they redefined terms, they would also potentially (attempt to) take away rights, which would make them very different beasts legally. It would completely change the legal landscape.

      No open source licence of any kind has ever put restrictions on the output of a program or of code. If he uses your code to make illustrations, those are his illustrations, as if they were drawn by hand, and he can do with or licence them as he pleases. If this wasn't the case, then every picture ever made with the GIMP would be GPL'd!

    The point of the GPL was that it was very simple and broad-sweeping. Naturally this does make it vulnerable to attack in the sense that the legal system might feel threatened by the massive impact of such a game-changing license; copyleft practically redefines IP law in a way that those in the legal institution (eg lawyers, judges, lawmakers, and the business interests that pay for them) don't acknowledge, understand, or otherwise feel comfortable with because they don't feel in control. All it takes is a mere technicality to disqualify the GPL from functioning at all, and the Free Software community is justifiably anxious about that, but the GPL has been successfully upheld in court time and time again, so I wouldn't worry.

    At this point there should be no doubt of the legal soundness of any version of the GPL, but it all boils down to a matter of principle. If a society believes in Free Software, then the GPL's legal application is perfectly simple and valid. To those hostile to freedom in the society, then the application of the GPL becomes something artificially difficult/problematic.

    A lot of the supposed ambiguity can be eliminated if you first look at the code as not being computer programs, but just being another written work, then evaluate any potential "derivative works" from that perspective, and let existing copyright law and case law guide the evaluation. Once you've done that, then look at the license-specific terms of the GPL regarding what it says constitutes distribution, as well as what it says triggers the requirement for distribution, and I think you'll find it's not nearly as convoluted as these two jokers are making it out to be.

    One thing that's often confused me is the exact relationship between the GPL and interpreted languages. For example, if I write a perl script which calls perl functionality which is part of the base interpreter, my script need not be distributed under the terms of the GPL. This is akin to using a GPL word processor or other software, where the output of a program is not subject to the GPL.

    If, on the other hand, my script calls a perl function which is itself written in perl (licensed under the GPL), the FSF argues [gnu.org] that this constitutes a derivative work akin to dynamic linking. Thus, my script (if distributed) must be distributed under a GPL-compatible license.

    I can see it both ways. On the one hand, calling a function written in the same interpreted language is very much like calling a function in a library from a compiled binary. On the other, it's strange to think that there's a distinction based on whether the function being called is written as part of the interpreter (in, for example, C) versus the interpreted language itself. In addition, there seems to be disagreement about whether the GPL really binds like the FSF claims. Lots of interpreted code gets released as the GPL when it seems likely that the LGPL is what the authors really intend; that is, they do not want to restrict scripts and functions which call the code.

    A good example of this is R [r-project.org] This statistical language has fairly small interpreter and a large set of both included and downloadable packages, themselves written in R (and licensed under the GPL). Clearly most of the primary authors do not intend for all R scripts using the most basic of functionality to be released in a GPL compatible way; for one, they make the header files necessary for writing C-based libraries for use in R LGPL to explicitly allow such libraries to be non-free. In addition, they are fine with a large number of downloadable packages which restrict commercial use (obviously not allowed under the GPL). Their interpretation of the GPL seems at odds with the FSF. Even if you want to release all your code in a GPL-compatible way, it may be (IANAL) that you cannot call both code restricted from commercial use and GPL-licensed code (basically unavoidable) in the same project.
