I haven't seen any other executive do a Nazi salute and some people won't buy a car based on the country of origin so I don't see why I can't dislike a brand because of its leader behaviour.

I don't know what the others think so I can't judge on that, but I can judge based of what Elon says and does.

And aside, Elon's been lying for years about everything and promising stuff Tesla can't deliver.

IMHO, there's a strong parallel between the Elisabeth Holmes/Theranos situation and Elon/Tesla.
