It's not just neurodivergence, but its that he recognizes where he jabs people and pretty much admits he doesn't care. I once had this conversation about with with ESR and I remember him saying "RMS doesn't care about the 'social overhead' of most person to person interactions" and so he kind of does his own normative preferences, thinking that because he finds them ideal, that others shouldn't be offended....but then he seems offended by an infinitely long list of things, and his intellect seems to treat this asymmetry as one big blind spot.

I've listened to him be rude to former co-workers (one seemingly on the basis that she was a woman in a technical role) and an absolute one man clown rodeo at various trade show events.

His philosophical brilliance has always impressed me, his personal presence is like rotting offal in the sun. He doesn't get the benefit of being remembered for the former when he puts in so much effort to broadcast the latter.
