Perhaps you saw the news about GM reaching an FTC settlement because they were tracking the locations cars they made at all times and selling the information to LexisNexis. You might have left the articles with a belief that GM agreed to stop. Their settlement allows them to sell precise locations -- but with 'anonymous ids' instead of names, and also allows them to sell data with name/personal information but only zipcode resolution location information.
