Richard M. Stallman, founder of the Free Software Foundation, delivers speech in rebuttal to Microsoft's recent campaign against the free software license. Stallman's speech is the subject of the history and future of free software movement.

Even companies that once laughed off it as software socialism have come around to recognize its benefits.
