Back when I was a student, there was a professor emeritus of communications who liked to say things like "communication usually fails, except by accident". The idea was that if you intend to say something but many people interpret it otherwise, that was you failure to communicate. Musk is certainly smart enough to realize that his tone changes the meaning of what he says, but he keeps doing it anyway. That makes him a kind of a troll.
The thing with trolls is that people often don't like them. They may barely tolerate trolls they agree with and actively hate ones they disagree with.
Musk reminds me of another person: a former communist (of the minority faction who supported the USSR) who later made a 180-degree turn and became a successful investment banker. He is one of the richest people in Finland who didn't inherit their fortune, and he is probably also one of the most hated people in the country. And he genuinely enjoys trolling. Often when business leaders or right-wing ideologists have something that needs saying but can't be said aloud, they let him say it.
