It's been a while since I've read this guy's whole story, but he was a bit more than your typical disgruntled customer, to the point of having a direct line of contact with one of Tesla's lawyers. The whole yellow screen issue, publicly encouraging countless other owners to fight the company via arbitration, "battery range issues" that couldn't be quantified and furthermore were not covered under any form of warranty when he bought the car, etc etc.
I have no interest in defending Tesla's abhorrent communications practices, but I think the final statement from the lawyer is quite clear and defensible:
"We aren’t obligated to sell you a car and we don’t believe selling you another car is in either of our interests. You’ve been repeatedly frustrated despite our best efforts and we are not inclined to continue doing business with someone we don’t believe we can satisfy such that they resort to threats repeatedly and/or disparaging us publicly. You ought to consider another EV or other vehicle and perhaps you’ll have a better relationship with their service team. "
I might say this is the clearest communication I've ever seen from the company.
Some customers are not worth the effort and need to be fired.
