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. Since the new owner bought it thinking it was a 90, because it was enabled to be a 90, presumably paid for it assuming this was the case and is now upset because they don't have what they thought they bought.
Sounds like all around bad decisions. The previous owner shouldn't have sold it as a 90 or at least disclosed that, "It's a 60 but Tesla swapped out the batter with a 90 and left it configured as a 90". Tesla, being notified, should have just enabled the 90 and made the customer happy. How exactly are people supposed to abuse this? Tesla put the 90 in there and they're the only ones who are going to be doing that. Presumably this cost them a fortune to do it in the first place. Why not get some good will out of it? "Hey sorry about your battery. We only had a 90 so we threw that in there. Enjoy. Tell everyone you know about how awesome Tesla was about fixing the problem and remember that next time you go to buy your next car"
