Why the keyboard in iOS 8 full access to the system?

With the release of iOS 8, users have received 

a number of new features that simplify the interaction with the system. But one of the most important innovations in the "eight" is the ability to install third-party applications that significantly extend the capabilities of the system. Now the owners of iPod, iPhone and iPad is finally able to install third-party keyboard. But why Fleksy, Swype, SwiftKey, and the like so urgently require Full Control permissions? 

To Apple's often make claims on the part of anonymized data. On one side of the scale - instant start and instant GPS to find your location, on the other - your smartphone (I want to believe that only he) always knows where you are. Rapid entry of passwords by TouchID, but now smartphone knows how to look your fingerprint. At the same time all this time remained closed iOS operating system. 

With the advent of third-party keyboards, do not permit full access also will not work. Why is it the developers? The authors of the popular keyboard SwiftKey tried to answer this question: 

"The need for full access is due to the potential performance and stability of the keyboards. Predictive settings, multiple languages ​​and themes - all it eats up resources smartphone and limited job application "in its own sandbox" leads to overloading memory. Opening up full access, the user allows the keyboard better use of system resources "

All developers as one, asserting that full access to the system is fundamentally different from the online-access, which is requesting applications from Google, Facebook and others. Well, it's very hard to believe because if the iPhone will know more and everything you write - you can forget about anonymity.
