That's what they tell you to get you to support the law, but in actuality they're trying to hobble Apple because EU companies can't compete (in large part because they have to deal with insane regulations).
This regulation is literally nanny state. There is literally a phone operating system that has 70% share in the EU that does EVERYTHING that the EU is asking of Apple. For those of us who prefer Apple's model, why are they taking the choice of that model away from us? Why is your preference for using an Android Watch with your iPhone more important than Apple's desire to not be forced to help competing products out, or my desire to not have 500 Apple engineers working on DMA compliance, but rather features that most Apple customers actually want?
