Apple keeps lying to defend their entitled and monopolistic behavior.
It's completely false that Spotify pays Apple nothing. Just like other developers, Spotify pays a yearly fee for the Developer Program, which according to Apple includes "all the tools, resources, and support you need to create and deliver software to over a billion customers around the world on Apple platforms"
You do understand that developer fee is most likely subsidized by the cut Apple receives from their cut of revenue. I wonder what the tools and APIs would cost if Apple didn’t take a % of revenue earned on their platform. How many people and companies wouldn’t be able to pay the fee, and then where would we be?
