Apple isn’t a sovereign state. It’s subject to US law. Sure it can challenge those laws if there’s a realistic chance of winning, but when there isn’t and they’re faced with a court approved demand based on settled law, not so much. They’re a consumer products company not an insurgency against the US system of government. Are you really saying you can’t see that distinction?

The link with accessibility is just evidence that when Apple says they do something to benefit their users because it’s their right thing to do and not for financial gain, that they have history on that to back them up.
