> I have absolutely no trust in anything Musk touches.
The other side of the great-man fallacy is the fallacy of attributing all of the problems with their works to them.
If you look at 1) the near religious following of Tesla enthusiasts for the company's brand, 2) the inherent superiority of electric vehicles over ICE vehicles for the vast majority of everyday use cases, and 3) until very recently no real alternatives, it's not surprising that Tesla was able/willing to cut corners on aspects of quality.
I also would never buy a vehicle from them either. I specifically waited until a good EV alternative to them was available in my price range. The faux-dystopian-bro turn they've taken with the Cybertruck is a cynical play on people's current insecurities, and Musk's recent revealing of his inner thought processes lines up pretty well with my long held impressions of him. I also think it's pretty unwise to have them be the sole domestic provider of manned space-launch.
Despite all that, given their current position most of his companies are acting rationally in their choices. It's up to his competitors or government to put pressure to change the situation. Arguably the government has stepped up in the EV space by providing a lot of incentives.
The situation at Twitter on the other hand does seem to be the most direct reflection of Musk's personality and state of mind. There's very little rational about what he's doing with it (much like his original purchase of it for an inflated price).
