It's not clear to be how strict the ban on sharing data is intended to be. If a person from Europe comments on a posting from someone in the US, or sends a private message, obviously data have to cross borders. Of course, many kinds of data could be stored more locally (advertising networks don't have to cross borders). But some aggregate information has to cross borders for an international company to do its bookkeeping. It seems that all of this could be worked out in a way that addresses Europe's privacy concerns.
