>The answer is right in the text you quoted. Because it's a different market than the smartphone itself and unfair competition. It's Apple using its dominant position in the smartphone market to prevent others from competing on equal grounds in a different market.*

Was that an unearned position due to regulatory capture or something, or did people buy their stuff, even if it's more expensive?

Is it even a dominant position with no recourse? (last I heard Android has more share in the EU and the world). Did they collude with Google and other smartphone vendors to not allow them to build and allow similar features themselves?

>With iOS Apple owns the playing field where all accessory vendors compete, and Apple competes on the same field

Isn't that playing field their own OS and device ecosystem, they build?
