WebMink writes "GitHub is a great open source hosting site, right? Wrong. There's no requirement that projects on GitHub provide any copyright license, let alone an open source one, so roughly half the projects on GitHub are "all rights reserved" — meaning you could well be violating copyright if you make any use of the code in them. And GitHub management seem just fine with this state of affairs, saying picking a license is too hard for ordinary developers. But if you're not going to give anyone permission to use your code, why post it on GitHub in the first place?"
