IOW, RMS is trying to push a political agenda and the prime mover for the entire system (Torvalds) is literally saying "No Thanks..."
IB4GE.
Stallman's Free Software Foundation holds the copyright to great chunks of the system, including the critical gcc compiler and some other 5000+ packages, as listed at FSF Free Software Directory.
You're missing the obvious basic logic that Linux needs Stallman's software to fully operate. Stallmans code will run on lots of software other than Linux, meaning Linux has a dependency on Stallman, not the other way around. Torvalds is no dictator either, whether he likes the sound of that or not, else he could switch away from Stallman if he had differences in philosophy, but obviously he can't.
My recommendation is use Unix instead, and leave these foreign/freeware clone headaches behind.
Essentially. And good for him.(torvalds)
We don't want nor need Stallman's crooked ideology.
