What options are there? Google Play, Apple App Store.

How much do they take? 30% and 30%.

Is there an option where they take less than 30% or where someone can compete on that cut? No.

Is there a different store you can use with the same privileges as these two stores? No.

Can you take your payments outside of the store and manage payment fees yourself so as to not give them 30%? No.

I doubt it's news to you, but Android openly allows app stores other than Google's.

It's does, but between Google's certification process putting restrictions on device manufacturers and the fact that usually those alternative app stores can't be installed from Google Play, asking side the untrusted sources scare tactic against users, and Google Play protect so closely integrated in the OS now, theyre not really viable market places.

At best I guess we could say Google has a carrot approach where Apple prefers the stick.

You don't have to prove active collusion. Tacit price fixing is still anti-competitive behavior.
