Not to be too simplistic, but who says that this is true? I am quite happy with the way that the Apple store exists. And, note, no body complained when it first began . . . and the rules have arguably not really change that much. But NOW, after they have created a large and enviable system organically, it is a problem.
Absolutely not true.
I've had a HUGE problem with it from the beginning. My first iPhone was jailbroken within minutes of the box being opened. My iPhone would be jailbroken now if untethered jailbreaks still worked.
It's MY iPhone, NOT Apple's iPhone, and they should have NO say about what software I install on MY iPhone.
I don't care about app stores at all. As far as I'm concerned, Apple's app store could take a 90% cut and only allow fluffy kitten petting apps as long as I can normally install software from any source of my choosing - which would NOT be Apple's stupid app store.
