I can’t imagine anyone that has decent prospects would agree to go back to Tesla after getting canned with those kinds of wild swings in decision making.
I think part of it was he had a really tough time dealing with California covid regulations for his business. It wasn’t something he could buy his way out of or pad someone’s pocket to make go away and they were very serious about it. In the same vein, that’s around the time his daughter came out as trans and you can see how that ended with her changing her name and completely disassociating herself from him. Combine that all with a slow (arguable) but consistent decline in the public’s admiration and opinion of him (which he craves desperately) and he began to crack.
Started running into things he couldn’t control or pay to go away and couldn’t cope I guess… I dunno
I can tell you, knowing people who worked with the guy since the original launch of the Model S, he’s always been like this. He’s always been a loud mouthed idiot, and he’s always been insanely unpredictable. The only thing that changed has been his PR team and personal handlers, and how much the news media is willing to focus on how much of a POS the dude is.
