A lot of people once upon a time trully believed the guy, so there's a lot who ended up feeling as having been swindled as they figured out more about the man and how most of his promises and his portrayals of the products of his investments were scam-artist bullshit, and that's a pretty strong feeling that transcends mere dislike.

Then there was a stage when only the most rabid fanboys still believed the guy and, man, those are infuriating usefull idiots with a cult-like view and fast and rabid at coming to defense of the guy. Those types along with TSLA small investors desperately pumping their stock like it was some kind of Muskcoin, did a lot more to turn Musk dislike into hate of him and his companies than they did to make people like and trust the man and his businesses.

And then as the cherry on top of the cake, came his coming out of the closet as a far-right nutter.

So it's kinda understandable that many don't just merelly dislike Elon Musk, they detest him, detest his cult members, detest the greed assholes pumping Musk-shit-stocks and thus genuinelly enjoy seeing the cunt directly or indirectly get shafted.
