I really wonder what will happen if Google/Facebook becomes unprofitable in EU due to regulations? It's clear that these companies work on user data and will not gain enough data/users/money if it is paid, specially social networking sites. Will they block it like China for exactly the opposite reason?
The interesting part about this is both google and facebook rely on network effects to ensure that they offer better services than competitors.
Even running at a loss may be worth them continuing to run in the EU to stop the rise of competitors and to keep the better service that having more users grants them.
