There's another common developer issue which these don't rectify. Apple gets 15-30% of the revenue for subscriptions and purchases through the App Store, whether it is an Apple-published application or a third party application. IMHO, Spotify's only really solid complaint is that it took so long for Apple to have a third party music intent. The rest of Spotify's list amount to them signing a contract with Apple having a contract stating that money for digital goods and services taken in-app or through referral by an app to another place (such as opening a registration page in Safari) require the payment to go through Apple, and Apple gets a cut. And Spotify repeatedly tried to cheat Apple out of this agreement. And repeatedly had issues where either the app version was rejected, or a deployed app version was given a deadline before it was pulled.
