"Now that Google has launched Friend Connect, we’ve had a chance to evaluate the technology. We’ve found that it redistributes user information from Facebook to other developers without users’ knowledge, which doesn’t respect the privacy standards our users have come to expect and is a violation of our Terms of Service.
