It's not about money; it never has been. The GNU project made money selling their software from the very beginning. It's about freedom, and how taking that away from people just because you can isn't a good way to behave. It's secondarily about the idea that pooled efforts give better results than divided ones.

For the anti-free software folks in this thread, I'd ask you this - why's Nokia going as far down the road of using and creating free software as they are if they didn't think it would make them more money than staying proprietary, even when they already had their own proprietary OS?
