Or they can leave, if they think that makes more sense for their business.
On the contrary, Apple does pay the money... to the artists. Which is something that Spotify doesn't do as much.

Strangely, despite this rather obvious market power (monopsony) that Spotify has in negotiating below-market rates with their suppliers, the EC has not seen fit to label them as a "gatekeeper".
I'm sure it has nothing whatever to do with having their headquarters in Sweden.
Spotify pay something absurd like 80% of revenue to the record labels (who theoretically pay artists).
And obviously Apple will need to invest more into their competing service to get scale.
None of this changes the fundamental point that Apple are self-dealing here, which might be fine in a world where they didn't control the app store.
