Please don't use RMS and ESR in the same sentence. That's as bad as using Free Software and Open Source in the same sentence. ESR coined to term Open Source to attack RMS's definition of Free Software, and they are mortal enemies.

Insofar as RMS considers Linus Torvalds a hacker or thinks anything positive about him, that would be because he made the Linux kernel GPL, not Open Source. RMS says of Torvalds: "Well, you can see that he is a person who doesn’t believe in freedom."
