We recently purchased a Tesla, but bought it used through a Toyota dealership. We purchased after the election, and actually raced to purchase at that point to capture the used EV tax credit. There was already an Elon stigma, though not to the extent that there is today.
Though I certainly don't like the associations that the car now brings, there's been no consideration of selling. I personally justify it by knowing that:
(a) We purchased used, and not from Tesla, so Elon didn't get any money from us. Sure, one could argue the second-order effect of slightly helping resale values, or that one day we might need Tesla parts/maintenance/charging. Hoping to minimize that.
(b) While the oil companies are not causing the acute pain that Elon is these days, they've been evil for a very long time, and will continue to be evil for the foreseeable future. Supporting them less, and contributing less to climate change is good.
(c) Car culture is terrible and destructive, and I mostly e-bike to get around anyhow.
Now, the random observer isn't going to know any of this, and we're going to have to accept that. I do have very little patience for people passing judgment on my decisions while ignoring the terrible corporations and people they're supporting with their dollars.
Ideally, we would've gotten a different EV, but there wasn't a great deal of choice in the 'used EV tax credit-eligible' bucket.
