Musk has accomplished some remarkable things, by having grand visions, ruthlessly executing on them, and being willing to repeatedly take on a massive amount of risk. If that had been all, I don’t think many people would be decrying him like this. It’s still easy to justify admiring those bits, if you’re so inclined

But he has also done a lot of things that make him unlikable and are harder to justify. He happily whips up massive amounts of hype, regardless of how likely his claims are to actually manifest (which is a large part of why the Tesla stock price is where it’s at). He sucks himself off at every possible turn, and takes dubious personal credit for a lot of things his companies achieve. He is vindictive and has exacted retribution on people with much less power than him (or pouts about it in an undignified fashion when the opponent is too powerful to crush, like the SEC). He has an easily bruised ego and lashes out in a very childish manner (remember the diver he called a pedo on Twitter). He enters into realms he has no expertise in and proclaims to the whole world that he has all the answers. He directly interferes in US and world politics by wielding his wealth and influence, sometimes with disastrous results (it doesn’t help that his political views usually are unsophisticated and immature, especially since he acts so certain of them). Etc, etc

Basically, he’s a dickhead that thinks he’s the best in the world at everything, and many of whose actions are detrimental to both individuals and the world at large. He doesn’t get a free pass for that just because he’s done some impressive things with his businesses
