The biggest issue is that Apple can compete directly with companies like Spotify without playing by any of the rules they force on their competitors.
The owner of a marketplace should not be able to compete on that marketplace without strict separation of power. Apple has huge advantages compared to Spotify when it can advertise any way it wants, doesn't pay commission fees, and can give itself priority for integration with systems like Siri.
