No no no, people are bamboozled into believing they can't get basic transparency, because <fill in some absurd excuse>.

Apple Pay charges 0.15%. App Store charges 30%. I want to see both on the receipt. This is not rocket science. I can see how much government charges right? The point is to show me all intermediaries which are getting a cut directly from the purchase. App Store clearly is an intermediary.

Tim Sweeney mentioned it as well - app developers cannot show cost breakdown in their own apps, it's an App Store rule [1].

That kind of rule you linked should be made illegal.
