narramissic writes "Back on November 29, MySQL developer Michael Widenius trashed Sun's decision to give MySQL 5.1 a 'generally available' designation in a now-infamous blog post. Widenius warned users to be 'very cautious about MySQL 5.1' because 'there are still many known and unknown fatal bugs in the new features that are still not addressed.' And now we get Sun's response. In an interview Monday, Marten Mickos, senior VP of Sun's database group, said, 'I learned over many years about the benefits and the painfulness of absolute transparency in open source. A little bit of debate never hurts. This is part of being an open-source company. ... People are free to blog about what they want.' Doubtless, this will do nothing to end the debate over whether Widenius will follow fellow MySQL co-founder David Axmark's lead and leave Sun."
