> Counter example to what? Why should they not be able to run both a relatively open ecosystem and a mostly closed one?

> I don’t think Apple is arguing that it is impossible to allow more open ways to install apps on iPhones. I think they’re saying that they don’t want to, and that they shouldn’t have to.

Apple volunteers the position that they couldn't possibly open the iOS ecosystem themselves, not just that they don't want to, making some very amusing claims in the process.[1] They also don't want to, but the more you dig into possible "whys", you get into a lot of troubling realities quickly.

Epic Games, on the other hand, is arguing that they actually should have to, at least to some extent. There are actually a lot of reasons why Apple's App Store practices might violate the law, and to my understanding, Epic Games is alleging that Apple's App Store practices constitute "illegal tying" whereby Apple unlawfully ties its payment processing service with its app distribution. That's far from the only potential legal issue that the App Store could face just based on current, existing law. (Note: I am not a lawyer, so take this with a grain of salt; but nothing I am saying is too original or groundbreaking.)

And of course, it's always worth remembering that what's legal today can be regulated tomorrow. I don't really believe lawmakers or the general public really have had enough time to take a look at the impact that Apple/Google app stores have had on the software market and decide if these practices should be legal. The EU seems to think they shouldn't, and while I don't agree with the EU on everything, I tend to agree.
