If Apple wants to charge 30%, fine, the companies impacted can just raise their iOS prices by 30% and pass it on to the customer. The higher cost of apps and subscriptions is not a tradeoff to buying Apple products. If customers see it as a bad tradeoff, they will by Android or WP7.
Instead, Apple is strong arming the content suppliers on their prices on other platforms. "make your price the same or less on our platform, or we will kick you off". That seems like the definition of anti-competitive. Why should Apple have any say what-so-ever on the price of pandora on Android?
If Google wants to pay Netflix and Pandora a fee so that their apps are bundled with Android phones for free, Netflix and Pandora could not take the money and give it away for free to users without getting kicked off of the Apple ecosystem. How is this not anti-competitive? Where is the FTC?
E.g. you sell the in-app "iPhone exclusive" version for $x and the out-of-app "everything except iPhone" version for ($x * 0.7) and then provide a "works on iPhone for no extra cost" special offer.
If Spotify was called Spatify on the app store, operated by a company that's owned by Spotify, their product wouldn't have to match the pricing of Spotify products on non-apple platforms... and perhaps 'Spatify' could announce a deal that allows Spotify customers to use their product for free.
Then it just comes down to whether Apple follow the rules by the letter, or apply common sense and tell Spotify not to take the piss.
I suspect if any company did this they would put a lot more research and thought into it than I have for my two quick HN comments - I'm really just wondering what, if somebody took this approach, Apple's response would be.
They're not legalistic, they're moralistic.
But the market is. No company is going to charge 30% extra on other platforms - competition would eat them there. So at worst there will be a split into Apple-only and No-Apple companies, at least for commodity repackaged content.
A possible solution could be to offer a separately priced subscription for people who want iOS access in addition to what's normally provided, and then keep the prices consistent in-app and outside. But I'm not sure how Apple would feel about a solution like that, it would be the closest thing to an explicit Apple tax we've seen, and it directly hurts the consumer (which Apple seem to care more about than hurting developers/"app store-vendors").
