Edit: As bm1362 says below they've since regained it, but it's still not best in class. From the article: "The Model 3 is now the fifth most reliable out of 12 luxury compact cars in CR’s ratings of predicted new-car reliability, just below the Audi A3 and above the Acura TLX and Mercedes-Benz C-Class. The Model S is the second-most reliable out of four ultra-luxury cars, just below the Genesis G90. "

If everyone starts to go full electric I think Tesla will become "just another car brand that was once first at something" similar to how Audi was champion of four-wheel drive at some point. I guess at that point they'll change their policies to better fit with the general public buying cars and used cars. Or the others will see an opportunity and go the Tesla-route and we as consumers end up worse off than before.
If the car had the license, and the car was returned and transferred to a third party dealer. Then the OEM decided that the entitlement no longer existed.
I'm not aware of any other scenario where a core component of a car isn't linked to the car. If Tesla didn't fuck up, they are applying Microsoft/Oracle software license terms to the car.
