This doesn't jibe with history. Or the present for that matter, see sibiling to your comment by btdmaster. Uses of data always expand, never contract. It doesn't matter that most or even 99% of the data is harmless, or that the data is useful, these companies are simply not trustworthy. The fact that no one asks permission up front (opt-in) tells you all you need to know.
