It was only a few months ago that the Hey thing happened, and that was all over HN. You can run a business entirely unrelated to iOS, release an iOS app because your users expect it, and then Apple comes in and starts making demands that you change your business model... Seriously, that's entirely unacceptable. And the Spotify and Amazon issue is textbook antitrust. Amazon won't sell ebooks on iOS devices because Apple will take 30%, which is too much for Amazon's commission structure. Apple also sells ebooks. Spotify has offered a music streaming service for years, and Apple demands 30% of every month's payment if purchased through iOS...and now Apple offers a competing service at the same price point.
