So far it seems Elon isn't welcome there, and while a 9% shareholder in a publicly traded company is huge, it ain't control. The tech industry is very different. A lot of those skills are hard to find. When your workforce turns on you, it can be a disaster. Plus the SEC is really on Musk's tail right now. At this level of ownership, they watch everything you do and can stop you from buying any additional stock in the company (because it is publicly traded). I don't see any changes there anytime soon, especially since he reversed field on being on the board.
