You want your TV ads to be more relevant, but you probably don't want someone living with you to report to the networks what interests you each day.

Is your analogy perhaps a bit ridiculous?

Tell most people that their PVR is going to report usage data and most would click yes in an instant. Most don't care if some faceless corporation knows how much American Chopper they watch. Many applications (including Apple and Microsoft products) start their journey with a user with the notification that usage data is going to be reported. I am just guessing, but I would wager that 99%+ click okay to that.
