He is a man who owns an electric car company but has been pushing climate change denialism as his political position and supporting politicians who do.
There's competition because Tesla is not the dominant prime mover it's valuation implies it should be, and people have sensed - correctly - a market opening. No one I know recommends "buy a Tesla" anymore for your first electric car - they say buy a Hydundai Ioniq or wait for a Chinese brand to get cheaper.
People are actively embarrassed to drive Teslas, which in turn means there's a growing market for "anything but a Tesla...". And because of that all of the actual faults of a Tesla are paid that much more scrutiny.
He showed his true colors, there is no correction possible, people just don't rewrite their core personality. Support for puttin' and overall war in Ukraine, support for dictators, very bad stance on many societal topics, treats his employees like slaves, proper piece of shit as a parent, utterly childish reactions of an immature boy rather than Man - we haven't seen the worst yet.
Brilliance in some aspects means nothing if its dragged down into mud by rest of personality. I know some still worship him for the positives and ignore or even appreciate the rest, I can't and won't.
As for Musk, he's a weird one for sure. He made me realize that I don't know the politics of most CEOs (or even know who they are). Which is just as well, I don't want to ponder in the supermarket whether my bodywash is ideologically consistent with my shampoo.
