This is a sensationalist article that reeks of pre-meditated biases. Yes the Facebook open-graph protocol has helped bring more traffic to Yahoo, but that wasn't an exclusive alliance. In fact nowhere in the Facebook press release does Facebook "congratulate" Yahoo.

If you read the NYT article, Yahoo merely warned Facebook about potential patent violations. There is no back-stabbing, this is business as usual. I wish Techcrunch would quit with the drama already.
