Linus Torvalds is also not a member of the FSF and does not "fight" for the 4 fundamental freedoms as RMS does. I saw Mr Stallman live in Berlin last Monday, where he gave a long speech about the freedoms, and the history of GNU. He is a very smart man, and has a vision to change society.
Mr Tovalds is also very smart, but not so worried about society and their freedoms.
