Google is taking a big shot at Facebook in the PR war over data portability and social network interoperability. I signed in to Google Friend Connect, implemented on the Go2Web2.0 blog, and saw this:

Google Friend Connect Diabled By Facebook

Normally, you wouldn’t list a service that isn’t a partner, but in this case Google chose to list Facebook and let users know loud and clear that they can’t connect to their friends on Facebook because the feature has been DISABLED BY FACEBOOK.

This is subtle in some ways, but in others it’s as big a smack as Apple’s brilliant I’m a Mac, I’m a PC ads.

Google is betting that hell hath no fury like a user denied access.

Probably a good bet.
