IMHO it should be on the automaker to learn about the destruction. They should have to carry it as inventory just like anything else. There should be real expenses to it, not just the ability to throw it out there with some tech that blocks it unless a user registers and pays the subscription, and not have to do anything about it. I think they should also be required to pay for repairs if/when it breaks. If they want to retain ownership of the heated seats so they can charge a subscription for it, then they need to own (pun intended) the responsibilities of ownership.

While I do think that's fair, my personal hope is that such a requirement would make them stop this asinine practice.
