In the same interview for the conference D11, Tim Cook was asked about the closed system called iOS and about possible changes that could be implemented in the future to allow users to customize it. In his characteristic style, Tim Cook said that iOS could become something easier to customize in the future, Apple going to give developers the possibility to manipulate more APIs, but don't expect something like Android OS.
On the general topic of opening up APIs, I think you'll see us open up more in the future, but not to the degree that we put the customer at risk of having a bad experience. So there's always a fine line to walk there, or maybe not so fine. We think the customer pays us to make choices on their behalf. I've seen some of these settings screens, and I don't think that's what customers want. Do some want it? Yes.
I found out last week that Apple is already testing the implementation of new widgets for the Notifications Center, of toggles for controlling the various functions of iOS, but also of panoramic wallpapers and Tim Cook probably refers to the same things. The idea of customizing terminals and offering a functionality similar to that of other operating systems will not extend beyond that, so don't expect anything else.
In the same vein, Tim Cook stated that iOS will not soon see Facebook Home from Android OS, precisely because most users would not want that system in iOS.
