Yeah its kind of strange the amount of backlash that he is getting. Is it wrong to criticize the launch? If you read his earlier medium post he even praises the Model X as a product itself.
well in honestly he does sound entitled just because he has money. The original complaints were that he elon was late and he should have served lunch at the event. Its like going to a Mcdonalds and not wearing a shirt or shoes. If they don't want to serve you they don't have to. If tesla, feels like this guy is being a prick, they don't have to sell him a car.
