In part, to be able to make sure everyone who plays has the best experience. We test on as many devices and as many versions of iOS as we can but depending on how far you go back that can be an enormous task. Limiting it to iOS 7 and higher (which is something like 90% of users) means that the testing lift isn't quite so heavy/crazy. And with iOS 8 just around the corner, fewer and fewer people are going to be on the older iOS versions.
In hindsight we probably should have limited the premium version to 7 and up too. (Or at least 6!)
