These are valid concerns that I share as a U.S. citizen concerned about my own privacy from government surveillance. It's appropriate for other countries to share them and to take action.
But is it clear that government surveillance by EU countries is more respecting of privacy? It seems to me more like the 5/9/14 Eyes countries are cooperating on just these kinds of intrusions. It isn't clear to me that Facebook data held on European servers will be any more secure from intelligence agencies than on U.S. servers ... including from U.S. agencies.
