Presumably Tesla's position in the face of that argument would be to just not give free updated features post sale. I'm guessing their reasoning here is "if you're willing to deal with some purple, we'll include the feature on your car too". Whereas older models like my 2017 S don't even get a bite at the apple. But the feature set on my Monroney sticker all works so I guess Tesla's part of the bargain is upheld and everything else is just gravy.
As an example of my point, FSD software drama not withstanding, they do seem to have a track record of goodwill upgrading hardware to satisfy the Monroney equivalent feature set. AP3 computers and AP2.5 cameras case in point. But giving everyone free MCU2 upgrades so that games and dash cam function obviously isn't sound business. Essentially you get all the free software "extras" up to the limit of your hardware set.
