I think the main point is the theft protection and protection from state. The US and the UK's democratic systems are broken.
In the US the social structure is slowly collapsing which increases theft and other petty crimes, at the same time the federal state has a huge surveillance power.
Solving the societal and political problems so there is less incentive having your iPhone stolen is hard. Expecting a state-like company to benevolently save you is the way they cope.
TBH without the EU, legislation like DMA would also be hard to come up with. The independent countries have less power to exert over American behemoths. This is the nice thing about EU.
