It is not just Apple. The UK is going after every company with their porn filtering laws. Imagine the response if people did not stand up to their tyranny and the Uk kept pushing their agendas further and further. This is why the UK needs to be broken up.
That's having the causation reversed. The porn filter laws are them breaking themselves up, because they're a hidebound own-goal and they're causing significant damage to themselves for no advantage.
But censorship laws and antitrust laws are two different things. It's possible for the same country to get one thing wrong while simultaneously getting a different thing right.
