curious, why do you think 30% is greedy? Are you basing this on a belief that the entire 30% is profit for Apple? Apple does not operate the app store without costs. I don't know if they detail their expenses in a way that would make them attributable to the store itself. But regardless, they have infrastructure, overhead, etc. that is paid for out of this 30% cut. At the end of the day, Apple's net on this fee is probably closer to the 15-20% range, maybe even lower. Server farms and huge solar fields to keep the power hungry server farms running is not cheap.
