Most people are irrational.
> Watch any interview with the guy
Interviews he's been invited to, where calling the operating system GNU has been stipulated beforehand.
rms is involved in GNU and has no involvement in "Linux". Not in the development of the kernel, nor in the philosophy behind the various "Linux" operating systems. What would you expect him to say about "Linux"?
A pedant won't cleave to his own private definitions when they suit him ("You said drm, which I call digital restrictions management"), common language definitions when they suit him ("when someone says sexual assault, we hear assault and think violence"), and technical jargon when they suit him ("it's GNU/linux"). There's no seeking of understanding there, just someone being pushy with definitions however it suits them.
2. I see no equivalence here. RMS will go out of his way to misgender people. He might not think that's a big deal, but that's no excuse. Watch any interview with the guy, even if he's talking to someone who does not subscribe to calling it "GNU/Linux" he will insist, every time, for it to be corrected. That's not just being insistent, that's actually - dare i say it - orwellian.
He also likes to draw the JBP "oh god no i have been misinterpreted" line. Like, when I say "Hacker news users are techbros." and someone asks me "why do you think all hacker news users are techbros", I can turn around and say I never said ALL I meant a very specific subset why are you misinterpreting my words you horrible horrible person aren't you supposed to be better this horrible tribalism. He does it in his per article twice (using the phrase "without inquiring if that's what I believe")
