I think it had to do with Google's recent release of their Web Accelerator that was released on Wednesday...

...A flaw with Web Accelerator, which Google acknowledges, can serve cached copies of private discussion groups or password-protected pages to people using the software.

For example, using the software, a Web surfer might call up a discussion group page and see the name of another group member, making it appear as if the surfer is signed in as that user. Web Accelerator does not cache secure Web sites in the programming language "HTTPS" such as banking or credit card pages, however, so data such as financial transactions are not at stake...

More broadly, privacy advocates are concerned about the scope of data collected with the Web Accelerator, charging that Google's privacy policy does not address some important consumer issues. Critics say the tool's capabilities to monitor a person's travels across the Web feeds into an overarching worry that Google is becoming a massive market research firm capable of collecting oodles of information on millions of people.
