It's ironic that the biggest obstacle to Stallman's idea of free software is his own stupid use of the word "free", so I feel I have to ask but do you mean free as in "without charge" or free as in "unencumbered"? Given that this is Hacker News, it's perhaps important to keep in mind that Stallman has nothing against commercial software. The whole "free" issue for him has to do with restrictions on the right of people to hack and redistribute their hacks.
