They hate him because Musk fought the law (Alameda County) and the Law.....oh wait, Musk won! He beat the sacred covid shutdown and has been blasting shutdowns and face diapers since.
This is all about Musk pulling his businesses out of liberal California and moving to conservative (for now) Texas. If he had done it quietly, I think, no-harm-no-foul. But instead Musk chose to make a public issue about the move, and I think that the liberal salons that inform the elites about what to think interpreted Musk’s statements as a sort of declaration of war.
