I love how you twist facts to make it sound like the event didn't start an hour and a half late.
I'm also not saying it was right for Tesla to ban him, that was shitty, but getting so angry over a late start and ranting about it in a blog post directed at Elon also wasn't a great choice.

He's a VC so he's used to people treating him like a king. He gets mildly inconvenienced one time and suddenly that's everyone else's problem? Nah, screw him. I would have done the same thing in Musk's shoes.
