App-Store Monopoly

Did... did Apple just introduce the equivalent of Unity's runtime install fee... but for all iOS app developers in the EU?!

And if you make a successful alternative App Store, and get, say, 100m people in the EU to install it, you'll owe Apple €50m/year as a "Core Technology Fee". NO GATEKEEPING HERE, EU! None at all! Full compliance, totally. Pinky promise!!
