The guy left at 9:00, 15 minutes after they started the event. Doesn't sound like he even tried to see it.
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.
