As much as I dislike Apple, their ecosystem works for them and their users. Unfortunately the general public isn't aware of the restrictions imposed on them until it matters, like when their screen is broken and they can't pay $$$ for a first party repair.
We need regulation coining and enforcing accurate terminology for the relationship between vendors like Apple and Tesla, and their users. It's not ownership. If I can't run whatever software I want on hardware that I paid for, I don't own the hardware.
Can you imagine if your mattress didn't work with third party bed frames? Or pillows?
