The complaint regarding the fee is not just that Apple takes such a large fee (which is reasonable for a one-off game where the exposure and back-end processing is beneficial, but is ludicrous for a recurring subscription from a large scale org), it's that you are restricted from offering any other payment options, or even alluding to possible other payment options. That is grossly anti-competitive and does absolutely nothing for consumers.

As a user of an iPhone/Mac/etc, but who loves Spotify, this whole thing just sours me on Apple a bit. Spotify works great with my webOS TV, and just about everything else for that matter. It supports everything. Its networking/streaming model is brilliant. The interface is much better than Apple music (with its bizarre integration with iTunes). That I can't use Siri to play a song is just obnoxious and turns me off of Siri, and whatever middle managers in Apple are pushing this are just doing themselves harm in the longer run.
