I only have a few friends who have purchased new or nearly new cars in the last few years. One of them did end up recently going EV. For all of them Elon was a negative factor but not the main deciding factor against getting a Tesla. The more important issue was Tesla's current offerings were not to their tastes/current budget/living situation. My friend who recently went EV got an Ioniq 5. Model Y was never even on her list, I believe mostly because of the driver controls.
I am sure for many people Elon has become so toxic that Tesla is off the table, but I don't have a good sense for what percentage of the population that actually is. I don't do any kind of bumper stickers, but I have though it would be funny to put a "Sorry About Elon" or an "Elon Sucks" bumper sticker on my Model 3
