Speaking for myself only: Musk actually delivered electric cars that work. You can buy one, it will likely show up, and it will do what it claims to do. Building one of the few successful (ie not out of business) new car companies in the last 50 years is pretty damn impressive.
I'd heard of claims of labor disputes and other unsavory stuff at the Tesla factories, but honestly, I don't know of a single car company in the world without a history of and ongoing labor tensions.
The self driving was obviously a fantasy and Musk got way over his skis on claims there, but he's far from alone.
Watching him drive Twitter into the ground has been a revelation for me.
