I never understand people who make this argument. Everyone has choice, go buy an Android phone and install/customize whatever you want. Apple has chosen what parts of their OS and user experience they control versus what part they let the user control. Personally I'm very happy with it because it gives me higher quality apps and some reasonable protection versus the alternative. If your issue is that you don't like where that line is split, fine, then choose a different platform like Android. Now if Android didn't exist, then your argument would hold more water for me.
