I mean, do we really need to enumerate the reasons for you? Next you will think it's okay for someone to manufacture a car that can't be opened when the 12V battery dies.
To address your main point, in theory at least, as a society, we should be able to tell government that something is not cool and address it as needed. The good news for Apple and most oligopolies now is that neither society or government can agree on.. anything really.
I believe what you describe is called democracy. The counterpart of which, where everyone "agreees" is totalitarian.
I guess you also think it's bonkers that car makers are required to put seatbelts in their cars.
if i buy an apple phone that requires a 9000$ magic charger that's on me
etc
What juicy revenue do you think they were going to get from iPhone mirroring to the Mac?
And the EU as a whole is less than 10% of their revenue?
Yes
Good thing governments are on the side of the consumer at least, right?
Users in the US and the rest of the world do have it.
And we talking about the same EU government that every other year tries to make it a law that there must be a backdoor in messaging platforms?
And the same Apple that puts them there: https://support.apple.com/en-us/111754
But hey, at least Apple is more principled than those filthy, corrupt and privacy destroying governments. They would never kowtow to a higher power, our stout and beloved Apple.
If Apple can't make those features interoperable, then they shouldn't exist at all. With Apple's size and access to development resources, there is absolutely no excuse for them other than greed.
