At this point I'm not sure what's left to be said. I had expected this as far back as March, actually. All the news stories talked about the ebookstores, but Apples vig applied to all the content distributors on iOS.
The really absurd part was that this outcome was completely predictable. None of the major ebookstores could have afforded to pay Apple's vig, so they had no choice but to tell Apple (politely) to go piss up a rope. And if you have Amazon and B&N refusing to comply, was it any surprise that other content providers ducked behind them as well?
I don't know if Netflix, et all could have afforded to pay Apple's vig, but I do suspect that Amazon's intransigence kept everyone else holding out just long enough that Apple changed the rules again.
And so Apple's greed has left us with this broken customer-hostile system where you can use the apps but you can't actually spend any money.
