(2010-11-06) Google Requiring Facebook Reciprocity

Google has changed its Terms Of Service so justify blocking FaceBook from its integrated "find your friends" feature, until FaceBook makes its Social Graph data equally available to outsiders.

Nov09: FaceBook has built a feature to support the method where users download their Address Book from GMail and then upload it to FaceBook to get the same effect.

Is Google's action now a response to the anticipated Facebook Messages EMail offering?
