Apple has improved the experience of phone and software for elderly folks and kids by giving them the Apple choice, where before if you wanted to use Microsoft Office, you either did it Microsoft's way or you don't use Microsoft Office (!).
Facebook can still communicate anything they want to customers through the channels <they> pay for. Facebook is also free to pursue any kind of financial arrangement they want with customers via channels which they can maintain and pay for.
But now through Apple's way, folks can have a one-stop shop to manage any runaway subscriptions, which is an unprecedented consumer benefit. Now folks don't need to maintain 10 different financial relationships... merely because they have 10 apps.
Before consumers only had one choice. Now they have two — Microsoft's way, or Apple's way. I'm still struggling to see how this hurts <consumers>, as opposed to the overarching story that Apple takes Very Good care of their customers. Without Apple in the middle, the Microsoft and Adobe's of the world each already have enough power to force customers to do things their way.
