I heard the same argument about providing personal health data, then CMS eventually started pushing Project Blue Button [0] allowing users to get api access to their own data. And that’s helped quite a bit.

There is risk, but saying that users can’t be trusted with an API to their own social graph seems to be throwing the baby out with the bath water.
