Earlier quoted context omitted.
It seems like a pretty clear duopoly to me, Apple and Android are the only two mobile platforms, and rather than compete with each other on price they are just both leaving their cut at 30%. Personally it’s not even the 30% I mind so much as, maybe there are cool new products like new mobile browsers that are just forbidden by the app stores and so we will never get them.
Amazon appstore, F-droid, Huawei app store, Samsung Galaxy Apps and so on.
Ideally measured two ways: in downloads and in dollars.
