Why doesn't FB let other businesses else access friend lists via API? or send people messages via API? Same with Google and all their data about you. They just can't do it.

FWIW, Apple is a monopoly as far as iOS app distribution goes. They act as if they own the relationships between app developers and their users. This stifles innovation. They also keep playing moral police even though they have no obligation to do this (as in, "you have to change the ToS of your service to be allowed to have an iOS app").
