"We do not share personal information with companies, organizations and individuals outside of Google unless one of the following circumstances apply:"
"We will share personal information with companies, organizations or individuals outside of Google when we have your consent to do so. We require opt-in consent for the sharing of any sensitive personal information."
Sensitive personal information: "This is a particular category of personal information relating to confidential medical facts, racial or ethnic origins, political or religious beliefs or sexuality."
All other personal data can be shared on an opt-out basis if they would like - it doesn't say anything to the contrary about this.
You could read Facebook's policy and make the same comment: "We do not share any of your information with advertisers (unless, of course, you give us permission)."
And, of course, one of the ways you can give them permission may be by using the site. It doesn't explicitly say how you give them permission anywhere on the policy.
On our new Policy, we state the facts simply. We don't sell your data in any case, and the only time we ever give it up is when we are being forced to by law. Big companies use legalese to hide and otherwise obscure facts from you and to grant themselves rights to your data that they shouldn't have.
Anyway, I'm not a lawyer and if you don't like our policy, don't use our site (as with any site). Whether or not I'm right or not about Google or Facebook's policy and what they intend, I still don't really understand how mentioning whether Google has a similar policy is relevant to the discussion at hand. We decided to write our own policy because we thought it was doing right by our users, and we encourage others to do the same. Our policy was not written to attack Google or any other company specifically and there's nothing in there that should lead you to interpret it that way.
