I think it's quite a smart marketing move, if nothing else. People do care about their privacy, but most aren't aware of exactly how much they are giving away when they do searches. It's only when you have fiascos such as AOL's accidental release of millions of search queries that this comes to light.

Try explaining to non-webmasters what information is given away by their browsers, and how much can be gleaned through cross-site cookies and web bugs. So long as you're careful not to confound them with jargon, most people are surprised.
