The problem is that’s not what the EU law says.

This feels a lot like a case where the EU may have wanted Apple to lose all their controls but they didn’t put it in the law.

Apple can still charge 30% (perhaps minus CC fees). They can still force you to be a developer in good standing. They can still limit what apps can do via their APIs. Heck they might be able to give App Store apps extra privileges because the developer choose the App Store.

If they wanted iOS to look as open as Windows or MacOS they needed to specify that.
