>a "delete all stored data on me and opt out" button

You mean like: http://www.google.com/settings/ads/

That's all the information the advertising network (Doubliclick) has on you (atleast, based on the cookie on your current machine). A more permanent opt-out: http://www.google.com/settings/ads/plugin

If you use other google products (GMail, Youtube etc), they let you individually delete your accounts. Or you can go here and wipe all your data: https://www.google.com/settings/datatools

Not that I'm a google apologist, but it sure helps if you do a cursory search (or click on the "Privacy" link on the homepage) before complaining about something they already give you.
