> If a competitor wants market share they have to build a better service.
Except when Apple ensures that it always comes out ahead when competing. It's not a level playing field.
Look at Apple Music vs Spotify - ignoring the self-preferencing iOS does to Appke Music, the App Store ensures that Spotify will always make less money than Apple Music. Spotify either has to hand over 30% to its competitor, raise its prices (and lose customers, while still paying its competitor), or just not offer in-app signups. Do you reckon Apple Music has to give away 30% of it's subscriptions?
It seems bonkers that the only option to have a competitive music streaming service is to make your own operating system or mobile phone. That's unhealthy.
