I am wondering if it’s really true, that Spotify pays nothing to Apple. If my information is correct every app provider needs to have at least one active Apple Developer subscription (in the case of Spotify there is probably far more than just one account involved). If it is true that Spotify pays nothing to Apple the only possibility is that Apple invited them to bring their app to iOS and granted them free access.
I know 99 USD is not what Apple is after, but it seems dishonest to not disclose this.
