It's not remotely like the mafia. It's like pretty much every other store in the world -- Amazon, Wal-Mart, Target, Macys, Newegg, etc. Businesses sell their goods to Wal-Mart even though Wal-Mart takes a 30%-50% margin because of the hundreds of millions of people that shop at Wal-Mart.
"I'm curious who produces the content like Financial Times that can just come in and supply a new native app for iOS..."
Is there no native app for WSJ, Economist, Fortune, Forbes, Bloomberg, Businessweek, etc.? None of those are as good as the FT but that's irrelevant, the FT isn't an option for someone searching for a business news/analysis app.
So are you of the position, that to users looking for business information, the delivery mechanism is more important than the content?
How universal do you think that is? How well do you think that will work when WSJ, Economist, etc, realize that they can ship a "native" app that uses a WebView, that also looks native, and they don't have to give Apple 30%?
And I really don't know how you don't see this being like the mafia... I own my own device, I own my own developer's license. My users own their own devices, yet I'm forced to force them to use Apple's distribution/payment/subscription channels.
I own my own store, or I distribute drugs on my own. The mafia forces me to buy and sell through them. Apple doesn't own a "financial news store", so acting like they should be allowed to (exclusively, no less) broker ANY content to their device, is frankly absurd.
Your analogy would make sense, except it's like Wal-Mart holding you ransom, telling you you WILL pay 30% and that you can't go elsewhere or they'll kick you out of their (App)Store.
