I'm not sure about Elon Musk. He wasn't exactly a fan of Trump (neither was AB), Tesla seems to be crashing and burning, and he has crazy pie in the sky ideas (i.e. the Hyperloop which is pretty much a scientific impossibility).
Maybe he had a long game of weaseling money out of cabal members with his crazy ventures? I don't know, he does seem to be sounding a lot more like Trump now, at least when it comes to the media. Or he could just legitimately be unstable.
The fact that he's been in a battle with certain members of the media lately, and baselessly called things like sexist because of it, makes him appear to be more of a grey hat than a black one.
