No 'smear' campaign was authorized or intended. Instead, we wanted third parties to verify that people did not approve of the collection and use of information from their accounts on Facebook and other services for inclusion in Google Social Circles-just as Facebook did not approve of use or collection for this purpose. We engaged Burson-Marsteller to focus attention on this issue, using publicly available information that could be independently verified by any media organization or analyst. The issues are serious and we should have presented them in a serious and transparent way.

You and your readers can look at the feature and decide if they have approved of this collection and use of information by clicking here when their Google account is open: http://www.google.com/s2/search/social. Of course, people who do not have Gmail accounts are still included in this collection but they have no way to view or control it.
