I am with Deozaan on this one. I created the account, I added the data, I continue to use Google, I inherently agreed to the plethora of privacy policies.
I fail to see the issue here. I know that Google has made various services which I now love and enjoy. Their search is fantastic, the email client, calendar, docs app and various other small tools are great. What do I care if the services I am already using, separately, share data amongst themselves?
