Nothing? It definitely pays all the fees to have access to Apple Development Program for all its iOS, iPadOS, watchOS, tvOS developers, it pays for all the Mac machines required to develop for iOS, iPadOS, watchOS, tvOS. Those are required to develop for Apple's platforms. It pays nothing because it cannot pay 30% of subscriptions to Apple and be a viable business, Spotify already pays out 70+% for royalties, if it had to pay another 30% for every subscription through the App Store it would be bankrupt.
