Agree about the sucking part. But IMO the problem is not that everyone will know everything about everyone. That would be weird (utopian?) but kind of fair.

The fear is about the rich and privileged knowing everything about the poor and underprivileged (using databases that are expensive, protected by IP laws, and/or require clearance), and opaqueness the other way around. Information as a means of control.
