It is an important distinction.

It’s the same with Facebook selling user data. Neither selling your data, like the carriers do, or selling the ability to target you with your data, like Facebook does, are very nice. But legally they are separate things that need to be regulated differently. As is the case with Flock and Palantir.

I'm not so sure Facebook is an apt analogy. Have we forgotten all the times Facebook has actually sold personal data?
