Richard Stallman believes all software should be free. Linus Thorvalds thinks it is fine that some software is free, but not necessarily that all software should be free.
This project has developed in directions I don't like. From the start, it was obvious that the Free Software Foundation was somewhat of a model, but the Definition has grown more extreme in this sense. The way the definition stands now, you can hardly be active on this website and then publish a book in a regular publishing house, the "common" way. So I'm off.
