You can easily argue the walled garden is for their user's common good, which it is. Less malware, safer experience, easier to use for less technically savvy people.

Only if there is no remediation - there is. Buy an android and quit moaning. "Freedoms." Laughable. Belarus is shooting people and you're mad because you can't force a company to do what you want when the free market can easily solve the problem.
You could argue that Microsoft bundling IE was 'for their user's common good' just the same. It was certainly nice and convenient, and made Windows easier to use. And it wasn't restricting anyone's freedom, because they could just use Unix instead.
Except none of those things are the point of antitrust law. But I guess who cares anyway, when genocide is always worse than these things, so we shouldn't care about them?
