It's clear that search engine use user 'feedback' to improve their search results.
But if
"Bing even sent Google synthetic and organic search terms, to analyze and make use of the results",
I would suggest they add 'powered by Google' to their search result page.
Further, I don't think it makes a difference if Bing is querying Google directly or using opt-in users to do so. In any case, their copying search results efforts from Google.

"copying" and "making use of" are not the same thing.
Again, I don't see why it's an issue for Bing to analyze and make use of the behavior of Bing toolbar users that opted in.
So what if their Google search behavior holds good weight as a metric?
