He who controls the past controls the future. That is how the pet consumer can be duped into believing that a supposedly 'new' feature is not merely a re-introduction of something that was previously taken away. Alternatively, they can be convinced that removing some basic feature is in their best interest because leaving said feature intact would simply be unworkable, despite the fact that there have been no problems with it to date (e.g removing microSD slot because it is too 'confusing' for the user).
