It's funny, isn't it. He's done a lot of good - kickstarted the electric car race, big batteries, home batteries, even done some good in the aerospace/satellite & communications field.
But on the other hand he's an obnoxious twerp and the US's worst boss, who sucks up to the US's worst president. Plus he's supportive of far right hate speech and conspiracy theorists, and turned Twitter into a Trump echo chamber, not to mention push/manipulate crypto currencies which are terrible for the environment and really only used by criminals.
Guess humans are complex creatures.
