There are other app stores on Android, e.g. OEM ones like the Galaxy store. The latter doesn't really compete on price though - 20% cut of one time payments and 15% of subscriptions. I think the Android app stores anchor to the iOS app store prices to piggy back on Apple's monopoly power - devs are used to having to pay Apple that much, so they will not resist if you charge the same.

Sure, but they also won't generally bother if the fees are the same as the installed-on-every-device Play Store
