Let's have some European competition
Why the hell was all this personal data going across the Atlantic in the first place? Europeans (for example El Reg for their lectures) have lazily been using American websites (such as Eventbrite) when it would be easy and entirely in line with the principles of Capitalism for there to be similar sites offering competing services in other countries. We should all take this ECJ judgment as an opportunity. It is time for all sorts of reasons to overthrow the American monopoly of such services. To Hell with Facebook, Google, Amazon and the rest of them!
