This will obviously have huge ramifications for book apps or magazine subscription apps that circumvent the Apple payment system. YUDU’s own communications with apple lead us to believe that these publishers will have only until as early as March 31st to ensure their apps comply with the guideline.
Yudu believe this is a good development, and they're somewhat correct. Having an in-app purchase option will improve the user experience, yes. But it also means that Apple will get a cut of someone else's sales. What did Apple do to earn that cut? Nothing. Yes, they developed iOS. So what?
The in-app purchase option was designed to get Apple's vig, nothing else. If the point really was the UX then Apple could have left the in-app purchase option open to anyone who wanted to integrate their own payment system, rather than tying it to iTunes.
This is like MS getting a cut of all web purchases made from Windows; it's that ridiculous.
