Re: Google are largely quite upfront about what they do.
Either you're very high up in Google management, or you're assuming that what they say is what they do. If it's the second then I'd suggest you become a little more realistic.
Blocking ads doesn't stop google following you around the internet. You need to block Google analytics first. While a site owner only sees analytics for their site, Google can follow your analytics cookie around the web. They don't publicise that much.
