I can see where you are coming from and once we have meaningful competitive alternatives to the AppStore (so after whatever they try in the EU with the platform fee and related shenanigans is forced to switch to a sane model) we can make a judgement on that.
Right now there is simply no way to know whether people are interested in the AppStore itself or simply selling to people who own iPhones (which is more likely but I may be wrong).
If I were a high class furniture company and the developer building roughly half of the populations' homes could enforce that all furniture sold to their customers needs to be vetted and distributed by them, of course I would play by their rules and even sing their praise.
Apples terms (all of them) are a direct result of their ability to stifle any competition on devices their customers paid them good money for.
Nothing they do is problematic unless they are able to "my way or the highway" their rules on the hardware level.
Apple dug too deeply and greedily and they woke up the sleeping regulatory giants which are now changing the rules.
