This is what the court said back then, but the court and the public were naive, and the future implications of such a rule were not yet clear. But even without hindsight, I think the court's logic was flawed. The phone company does not publish a list of who called whom for all the world to read. We would be justifiably outraged if they did. That's the test we should use in determining if information shared with a company is "private". Just like I expect the phone company to keep my payment information private, I also ought to be able to expect my call history is private.
