You know, it's a funny thing, how to define anticompetitive and monopoly practices, depending on how you frame the scope of the market. See Peter Thiel's book for a chapter on this. You could say that Apple has a monopoly over developers building apps and providing their services to people using iPhones. But is that the scope that is under regulation, or what constitutes the "marketplace"? Someone else looking at it could say that Spotify has a multitude of ways to provide its content to customers -- web, it's own Windows + Mac desktop apps, Android, etc. Would you claim that that is lacking competition? Which way is a regulator supposed to look at it?
