> people stop using Facebook in that condition. You've failed to understand the example. Nobody would have to change ISPs to use Facebook because Facebook paid off the ISPs for some form of exclusivity. It is Facebook's competitors who would struggle wity user acquisition because not only do you have to convince users to change ISPs to use your competing platform, but you have to convince all your frienda and family to switch too if you wanna be able to call them. > It sounds completely unrealistic You are incredibly naive then. This sort of thing regularly happens all around the you. Kickbacks, exclusivity and companies colluding for competitive advantage is commonplace, not unrealistic.
