That would be a more fair criticism if Apple charged the game publishers fair fees commensurate with the cost of security audits, bandwidth, availability, and the like. Instead, Apple (and other app stores) tend to demand massive profit sharing.
WTF? Profit sharing? That's just a daft statement. Apple has a surcharge on transactions through the App Store. There's no further requirement from developers. Big devs take issue with Apple's fees because instead of considering the fees the cost of doing business they act as if it's some sort theft. App Store transaction fees amortize the costs of development/operations of not just the store itself but the OS it all…
Considering how Apple makes almost 50% hardware margins on every iPhone sold, I think they make plenty enough to continue software support off the initial hardware sale alone.
