This definitely will happen. Like 100% sure. It happens right now, the beginning. And facebook won't be some magic data provider, maybe they'll supply 1-2% of all data if the company will survive for so long at all. Behavioral prediction will be Very precise. And you won't be able to anything, all endpoints will be controlled - ISP, cell operators, physical stores that sell hardware, banking, payment alternatives (bitcoin etc.). They are mostly controlled now, there is just no such precise and powerful analytical programs.

This won't be end of the world or the internet. Not even close to it. Things just will be different in the future and people would accept them.
