If you own an iPhone, you've got a ticket and are inside Apple's themepark. You can't leave until the end of the day, or you get charged extra (ETF). Suddenly, Apple pisses off the vendors by killing off their profits. A couple of the vendors talk about going to a different, more open theme park once its announced. You're stuck inside Apple's park, and you're hungry. But the pretzel guy just left because he can't make a profit selling pretzels in Apple's theme park. Why should I be happy as a customer here again? Because Apple's made it so I can pay the pretzel guy (who is no longer here) slightly easier?

OK, pretzels. Your analogy looks like this to me: Pretzel guy has a stand inside the park, where he gives away pretzel tongs for eating hot pretzels. You want pretzels, he used to give you his mobile phone, you'd make a call, give somebody else your credit card, and the pretzels would be delivered to the park.

Now Apple says that (1) he has to sell the pretzels inside the park if he also sells them outside the park, (2) he has to charge the same price, (3) Apple muscles him for 30% of his action on sales inside the park, and (4) he can't have pretzels from outside the park delivered to you in the park. You actually can buy pretzels by phone from his store in the park, or with your web browser, but he can't put the link to his pretzel store or the phone number of his pretzel store on the pretzel tongs he gives away.

If pretzel guy can't make a profit, he leaves. If enough vendors leave, the park is less attractive and fewer people buy tickets.

So yeah, maybe as a customer you won't be happy if pretzel guy can't figure out how to make money at Apple's expense. And yeah, maybe as a developer you aren't happy if you can't figure out how to exploit Apple's customers without Apple exploiting you. And maybe everybody goes somewhere else.

Seems like the free market at work. So what's the problem here? You have choices, exercise your right to choose.
