For the first time, court lays down a legal foundation for the protection of open source developers. This means now all open source licenses are enforceable. From the article:
An appeals court has erased most of the doubt around Open Source licensing, permanently, in a decision that was extremely favorable toward projects like GNU, Creative Commons, Wikipedia, and Linux. The man who prompted that decision could be described as the worst enemy a Free Software project could have. This is the story of how our community was able to benefit from that enemy.
For a decade there'd been questions: Are Open Source licenses enforceable at all? Are their terms, calling for a patent detente or disclosure of source code, legal?
