Joe Wikert has posted a pretty strong complaint on his Publishing 2020 Blog:
I'm certainly not the first to blog about this and I doubt I'll be the last. What I can't understand though is why, after Apple made in-app subscriptions possible months ago, are none of the big guys selling their magazines that way?
Does it have to do with Apple's 30% cut? Are they all trying to find a way to get around this and sell direct? That's what Amazon does. When you buy a Kindle edition via the iPad app you're actually just going direct through the browser, not buying through iTunes. I'm assuming Amazon therefore doesn't have to pay Apple a cent on the transaction. Why wouldn't magazine publishers want to do the same, especially on longer-term subscriptions?
