Turns out the EU is making Apple offer alternative app stores and app side-loading. Which is a good thing. But Apple will still notarize (review?) apps shipped through these stores. Apps must be the same among stores. Devs of third-party stores that use Apple Pay will still pay a 30% fee per transaction. Apps that ship with different payment systems are still required to pay a 17% fee. After 1m annual installs, Apple will also charge $0.50 per install. As far as we know, there are no exceptions for open-source projects. All of these, of course, after paying for your Apple Developer account and only for the EU. 

Apple is like: you can have your bigger pseudo-freedoms, we just want money. Lots of it.
