Now, to your point. Do you really think MSFT just designed a machine learning algo that just evolved to predict >www.google.com/search?q=thisisafakequery> to <www.somepage.com>? Come on.. If I were the Bing Toolbar PM, I would spend half my manpower in making sure that I'm extracting Google's results.
And then, you have all the messy issues about who truly created the association between queries and results: http://news.ycombinator.com/item?id=2170832
And also, the big competitive issues you have from MSFT's abusing its dominance of the desktop (what's the HHI of the OS market again?) to compete in another area (dominance of abuse, as someone said: http://news.ycombinator.com/item?id=2167016 )
Really the only valid argument you've implied above is that it might be unethical to strip data using the Bing toolbar. But that's an entirely different point. I'm not saying Bing is being ethical. I'm just saying they aren't directly copying.
