It seems people today are okay with trying to weed out anyone who they think is "wrong" from being able to communicate. That scares me more than Elon tweeting.
I strongly believe it's good having "crazy" or "wrong" people challenging the norms, especially when they have good intentions and contribute meaningfully to the conversation. Society has always had these sorts of people on the edges/fringes and the world didn't end. Frequently they helped move things along for the better.
That doesn't mean we should kill any conversation before it even starts - or, even crazier, calling to prevent them from running their own companies because they express unpopular opinions in their spare time.
Elon is the one that leaked/lied about Saudi investment money, or chose to call a rescuer a pedophile (and by extension all expats in thailand pedophiles) just because the man in question was focusing on saving kids and couldn't be bothered with Elon's constant attention seeking during that crisis.
High executives being incisive, direct and sometimes not socially good enough is expected; only the best of the best manage to do that (one exemple in the tech world would be Gates). But being insulting and losing control is not.
