Google has something to gain from all this. Consider the implications to Bing/Google competition for marketshare in the following scenario: MS decides to bundle and auto-install the Bing toolbar in IE. Also default opt-in to the "share clickstream data with MS" option. Now you have tons of users with the Bing toolbar _and_ using Google to search. MS could "use" or "copy" the results of Google's hardwork on search and pagerank and consequently provide some serious competition for search marketshare.
