I have to wonder whether at some point the EU is going to become so aggressive that the big US tech firms really do start calling their bluff. Stronger legal privacy protections may be long overdue in our modern, online world, but that particular measure is transparently aimed at undermining entire business models that have supported services evidently valuable to literally billions of people around the world, and that may be a bridge too far.
If the likes of Facebook and Google all turned off their services across the EU for a day, and replaced them with a SOPA-blackout-style message explaining that they can't afford to continue providing services without the ad model that pays for them, a lot of people would notice, and the EU probably wouldn't get nearly as easy a ride afterwards. I don't know how much damage would be caused if those same big tech firms cut off EU citizens permanently, but for better or worse, very many people now rely on the likes of Facebook and Google Mail for their everyday lives, and I'm betting the damage would be worse to the EU citizens than it would be to Facebook's and Google's financial statements (assuming the alternative is that they continue to operate but with a heavily damaged business model).
