True, but most CEOs are unknown to consumers, only to employees and share-holders. Usually there is a “culture” of a company that is a blend of PR, advertising, marketing, etc. Here Musk became associated with the brand though. Tesla existed before Musk and worked well… but was nowhere near a popular. I hate Musk yet I feel it’s fair (and please if you have data showing I’m wrong, do share, I’d love to remove any wrongful attributed credit from him) to say he made Tesla enormously more popular than before he invested in it. So… you are right in most cases people buy cars, and other products, without knowing about the CEO but that specifically does not apply to Tesla where the hype precisely came from a self branded as IronMan.
Costs 1 EUR and takes 10sec to put a sticker on a Tesla that says “I bought this before Elon went mad” and plenty of people on Lemmy would understand I bet. It’s more of a gesture to show that one having a Tesla does not support the actions of the its CEO. A Tesla without even a sticker on is assumed to be owned by someone who knows yet either does not care or even supports Musk.
