What I don't understand is why so many devs choose to accept Apple's rules. These devs know full well that they will likely be f***** over like this in the end. Yet they still give Apple their business.
Much higher rate of sales (apps and IAP) and subscriptions than Android. Not sure how the ad market looks (I've not worked on ad-supported apps) but wouldn't be surprised if those—at least in some categories—also pay so much higher that they're more lucrative on iOS, too, despite the smaller user-base.
