I question the assumption that this is zero sum. Just because Apple makes money doesn't mean they are taking it from developers.

If you're still stuck on how unfair it is, I encourage the you to move up the risk chain. If you want more of that 'river of gold'; All you have to do is design, manufacture, distribute and service complex devices across disparate networks globally. Do this better than anyone else, and then you can decide how fair you want to be. Don't forget that anything short of the top three and you've probably wasted a large fortune.
