So the way I'm reading the post is Tesla swapped out a battery pack for a 60 with a 90 and enabled the 90. Tesla, years later, discovers that even though the hardware for a 90 was installed it should have been software limited to be a 60. (I'm assuming that Tesla only made the owner pay the cost of the 60 battery swap even though they replaced it with a 90). They go and "fix the glitch" and set it back to the 60. Sin…
To be fair, for people not intimately familiar with the craziness of modern tech business, it's reasonable to assume that whatever capabilities the car has at the moment of purchase, are going to be there indefinitely. On the face of it, cutting car battery remotely via software patch sounds about as reasonable as remotely removing a room from a house you purchased.
