I don't think this is as unethical as you say. I sincerely believe all Bing is doing is using the toolbar to get (long) search trails. Using search trails is a near-standard practice--to guess intent, find deep links, yada yada. Does Google want Bing to special-case links going out from their site? Or all search-engines maybe? What about techniques like this? http://www2005.org/cdrom/docs/p66.pdf http://www2005.org/cdrom/docs/p66.pdf The paper authors sure call it innovative, not cheating :) (Also, techniques like this search+wrapper are great for Product Search, and I'd be surprised if Google doesn't use them). I think Google's stance is rather unfair. While Bing may have "copied" results, I feel this was just a side-effect of trying to build a good index, rather than a case of "oooh.... let's see what's google returns for this, and just copy the result").
