That's not what Spotify wants. If that were so, they'd want me to pay Universal Music, Sony, et. al. directly for streaming music. Spotify is not the manufacturer in this case – they're the distributor, just like Apple. But unlike Apple, they're forced to pay a 30% cut of their revenue. Were Apple not the platform owner, and were this 30% cut not an obvious and significant competitive disadvantage for Spotify, this wouldn't matter. But they are and it is, and this is where the problem lies. Spotify has a strong argument that Apple is using it's position as the platform owner to stifle competition, and I believe that eventually they'll win that argument.
Epic, on the other hand, has none of this and is screwed.
