The FTC settlement with GM allows GM to sell precise location as long as it's anonymized by attaching it to anonymous identifiers rather than personal info. It also allows non-precise location (e.g. zipcode/census-block) attached to identifying information.

Apparently no one at the FTC is smart enough to realize if Bob and anonid both move through the same sequence of approximate locations that the anonid is Bob. Or maybe they aren't that ignorant and just wanted to look like they were doing their job while protecting the surveillance status quo.

The government measures success in column inches.
