> Twenty years ago, if you had asked people: "If you had a service that data mined the information you gave it for advertising purposes, where potentially dozens of engineers and operators have access to that information--would you consider that a trusted and private system?" They would have said "no."

With the upside that every product is free and said service have never used such information malevolently? That's a resounding 'yes'.

The question is not "would you use the service" but "would you consider the service private?" How does being free bear on whether it's private?
