I posted this above - How long then for FB to develop apps or acquire apps for the dominant use cases, and then squash out/limit the competing apps that integrated and helped build up the user behaviour to begin with? There's no way FB won't do this, that is part of their behaviour. How could they do this? They could all of a sudden require apps to use their payment, with whatever % taken that they please, and if you don't agree then they boot you and tell all of your users about their replacement app.
