What exactly, and please be specific, do you think Apple is doing that is wrong? It is not clear from your comments.
Rumor is, Amazon was cut a deal and others have had a deal so the rules don't seem applied in a fair way. Amazon isn't forced to use Apple Pay for example. (which i think is the part specific with this specific case)
in fact, it's safer than Youtube if safety is a concern...
Amazon didn't cut a deal, you can't subscribe to prime video in the app without using Apple's IAP payment system. You can only subscribe outside the app.
Most developers who use Apple IAPs gave to give Apple a 30% cut. Amazon only gives apple a 15% cut. How is that not a deal?
