I'm sure there are reasons, but it stings a little.
Green bubbles can be worth a few hundred dollars. Or why some people keep a busted iPhone around just to manage the parental controls. Android doesn't have much of those restrictions or it applies less.
I'm sorry, but what? To whom? I have an incredibly hard time believing it's actually something which makes a concrete return on investment, but maybe I'm wrong and the world is even dumber than I thought.
