They also take 30% of every app you sell. The fact I bought doodle jump underwrote the developer tools. As of this year they are the single biggest mobile company due to their app and phone sales. The $100 a developer isn't much of a profit for them as it is a means to control access.
Neither do I, I'm just saying it's making them very profitable, much more so then the developer fee.
So much more that I don't see the developer fee as a source of income.
