Where's the Google integration in the Facebook UI anyway? As this article points out, there isn't one. They don't have a Google search box. They don't use Google's index for their internal search engine. So, what could Facebook change to deny Google referrals? Disable outbound Google links in people's feeds? That seems implausible, and I'm putting it kindly. This isn't Mozilla switching to Live Search for the default search provider. There's no partnership that could really be broken to hurt Google.
