The original iPad was rendered unsupported after 2 years on the market. At that point, the lack of software updates combined with inevitable unknown security vulnerabilities mean that Apple's model actually generates a safety hazard.
It's common for Android hardware to become unsupported after 2 years, but the degree of success of cyanogenmod and postmarketos (and now project treble) demonstrate that there is a better way.
As time passes, an iPad's unknown vulnerabilities become known. Similarly, the scenarios and environs in which a Tesla is driven also change unpredictably.
Apple and Tesla can't support their designs indefinitely and remain profitable. The ethical solution is either don't sell the product (rent it out instead) or simply allow owners to accept the maintenance burden.
