There's an argument for the CEO's ethics and values to strongly guide the company.
If engineers sharing your views and concerns don't want to work there, how are you expecting those cars to fulfill your expectations and perform on the points you value ?
If this were something like bread or water, then yes. But it's not. A Tesla is a luxury purchase, not an essential purchase. Nobody who chooses not to buy one because of Elon's stupid antics is going to suffer in absolutely any sense.
Sure but there's still plenty of time to see if those histories will be the fawning sycophancy required by the totalitarian regimes he openly advocates for, the story of a brilliant businessman who was batshit insane (a la Ford) or the humorous tale of a fool who lucked into a few $billion and then squandered it all on an empire of trash.
Musk may be an asshole boss and he may post cringy right wing opinions on X, but trying to boycott his businesses based on those actions is quite disproportionate compared to the behaviors whole industries are engaging in regularly. Elon and his companies are in no way worse for the world than the average car manufacturer or businessman.
People factor a lot of things into major purchase decisions, and it's really not a big deal to refuse to purchase a vehicle from one or more car companies. Some people will only buy a Honda, for example.
Personally, I don't want to fund Elon Musk's culture war bullshit. I don't like being lied to (FSD, and vehicle reported range). And I don't like their doing away with all of the instruments in favor of voice control and a single display.
