Accusing a guy to be a pedophile with zero evidence was one thing. It's just a pretty asshole thing to do, especially when you have millions of followers and can ruin that guy's life with a tweet. https://www.theguardian.com/technology/2018/jul/15/elon-musk...
It was indeed a pretty asshole thing to do, but so is telling someone trying to help to 'shove it where it hurts' and as far as I'm aware, Musk is the only one of the two to have actually apologized for being an ass there.
He seems to be a guy that acts impulsively. But, being somewhat of an asshole once or twice over the years is hardly worthy of the passionate hatred some people have for him. It is more about greed/envy/etc. imho. The world is a more interesting place with Elon in it, from my point of view.
