Let's not forget that you can't buy Kindle books on iOS because of this policy. Apple wants 30% of the cost of every book, which would kill Amazon's margin. (Of course, this is just businesses fighting over the lion's share of the money; the publisher is only going to give the author ten cents on the dollar in royalties anyway.) But Apple will happily sell you books in their store, which smells like anticompetitive behavior. Steam Link faces a similar issue. Apple, apparently, considers buying desktop games through an app that can remotely play them on your phone to be the same situation, and demand that payments go through them.
