Look, those people were never going to be supporters of the brand in the first place, anymore than the folks who despise Apple (fill in company of choice).
I’ll never buy a Ford. Never have, never will, never had a positive thing to say about them. That’s based on nothing Ford has or has not done. It’s not based on adverts or people telling me they suck or vehicle safety or recalls or anything tangible. Their brand could never get better in my opinion even if they made an aluminum pickup or an EV and not even if they rescued kittens.
It’s the same for all the Tesla haters and most of the FUD believers.
The people who can damage a brand are the ones who support it and believe in it and then don’t. Think about that for a minute; the difference between that group of people and the ones you think are damaging the brand, who never had a good thing to say about it in the first place nor cared to.
