This might come as a shock to you but most people do not care what the political opinions or behavior of a car manufacturer's CEO are. Likewise the internet does not at all reflect the views of your average person, and I would wager that despite Tesla fanatics being very aware of Musk and his eccentric behavior, most Tesla owners moving forward won't even know or care who the CEO is as they rollout to mass market. This won't make a dent in his customer base. Musk is beyond reproach at this point, his "fuck you" warchest is too big.
