I don't know that much has been written about this yet, but consider data portability as one example. If an EU court rules that Facebook must allow extraction of a social graph with an email address and consistent ID included for each contact, it dramatically weakens their network effect and lowers the barriers to on-boarding users onto competing social networks.

In that scenario I could also write a quiz app that gives you your personality based on that export. That would be an amazing data set for a researcher at e.g. Cambridge and an example of the EU supporting researchers.
