I run what would be considered a small app company, compared to huge companies like Spotify. I have no issue paying Apple a commission for App Store sales, including in app purchases. I know a lot of other small developers and do not know of any that really have an issue with the App Store fees. The only developers that appear to be jumping up and down about App Store fees are the large companies like Spotify or Epic Games. As a developer, I prefer the "walled garden" approach, as we also have Android apps, and we have to deal with copycat apps all the time on Android because you can "sideload" apps. With iOS, this has only come up once, and Apple quickly took the copycat app down once we complained. With Android, if the copycat app is not being sold through Google Play, good luck getting it removed. For those that think that companies like Spotify should be able to make billions from iOS devices whilst only paying Apple a $99 yearly developer fee, you truly have no idea how much Apple actually invests in iOS. The differences between Google with Android and iOS are night and day.
