I think it's a lot more nuanced than that. Should we, as a society, allow companies to lock people into platforms, and discriminate against those who have decided not to fall prey to that lock-in? Especially when avoiding that lock-in (which is often a passive financial/economic choice, not an active rights/freedom one) actually causes social and emotional harm (the whole "green bubble bullying" is a real thing; yes, I think it's dumb too, but what we think is irrelevant).
Personally, I think the answer is "no", we should not allow that sort of thing. Profit is not the most important thing in the world, by far.
Your car analogy falls flat, as is the case with most car analogies. No one would expect to get free service at any garage, and that is unrelated to the topic at hand. You can go to any garage, and they're mostly not model specific; even when they are, there are plenty of third-party alternatives. (And this is why locking down car hardware/software such that only the manufacturer can provide service is a garbage practice that we should legally disallow.)
Google makes that money by spying on people and using that for ads.
Apple makes that money by selling hardware.
You're saying that both companies should be required to provide the services they render, but apple's model of paying for it by selling hardware should be banned.
Also, go talk to someone who has bought a new car, and ask them how much their servicing costs. If they go to their manufacturer's service centers the regular services are free for the first few years, but if they go to an unrelated mechanic it costs money.
I do have a spare iPhone in a drawer, still works and can message on iMessage. There, I have purchased Apple hardware, now can I use iMessage on my Android phone?
For the same reason that if you buy a game for xbox, and then when you later buy a playstation you can't turn around and demand that MS port the various xbox services to the playstation, or a publisher port an xbox game to playstation.
