One of the major reasons of existence of the EU is to provide a common-level playground for everyone, where everyone has a reasonable chance of success based on merits. Forcing Microsoft to break up their anti-competitive bullshit back in the IE6 days was a good thing, and so is breaking up the engine and app store monopoly on Apple's side today.
Another reason of existence is waste reduction, and holy hell did the EU do a good job there by getting everyone sans Apple to agree on micro-USB, then on USB-C once it achieved reasonable market penetration for everyone including Apple.
These days I only need to carry two USB-C power bricks from Anker on vacations to charge everything I have from my array of phones to my laptops (corp and private), and once I find the money to upgrade my Sony camera, that as well.

Yeah, I wonder how secure those customers would be when any kind of third party app store can just show up and start releasing data stealing, virus-infested apps, with no oversight?
The idea that allowing a wild west of things because "freedom" is somehow better for the end customer is very shortsighted. I've never had to assist anybody in my family who has an iPhone, that cannot be said for Android however.
