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.
If you don't like Musk, why would you contribute to his success?
