As someone who owns a Model 3, I hate how Musk constantly comes up when talking about the car (and never in a positive light). Frankly I find the brand so damaged now because of his behavior, that this will be my last Tesla. I don't want to be pushed into an "right wing" category simply because of a purchase decision I made 5 years ago.
Sure there are other factors, such as more competition, and overall a slowdown of adoption of EV cars, but I have am fairly certain that Musk is one of the big factors of this sales drop. Price/value wise I still find Teslas incredibly attractive. This would be an interesting topic for a big survey if my opinion is in any way representative.
