I find this argument kind of ridiculous - yes, app developers (such as Spotify) bring value proposition to Apple's products by being available on the platform. But, apps (such as Spotify) probably wouldn't exist and wouldn't have access to the immense value of an App Store and its tooling if Apple didn't exist.
Luckily, by custom there is another solution - respect each other boundaries and stop acting like whiny little children.
