Well, I'll give my own impression: I was never a fanboy, but I think his PR team did a good job making him seem vaguely non-threatening and focused on bringing the sci-fi ideas into reality. I remember rolling my eyes when he appeared in Iron Man 2, and the "Tony Stark" comparisons always seemed, to be charitable, aspirational. But then he started tweeting about that cave diver being a "pedo guy," fired his PR people, and it quickly became obvious who he really was.

Basically standard tech bro protocol. Appear neutral on politics and vaguely altruistic in motive, until they have so much money nobody can stop them from being their worst techno-fascist selves. (Altman seems next in line for this transition.)
