So what exactly would a control that satisfies you be? How about I submit search terms on the computer terminal that connects to a server that isn't even on the internet. There, those searches do not end up affecting Bing.

The fact is that they used unique search terms that link to unique subjects. They ONLY submitted searches using what they described. That means the only places those searches passed through were the OS, toolbar, IE and Google. They know Google received those searches, did it propagate to Bing?

That's it. They didn't need to offer a placebo to anyone. It's like throwing a ball and hearing an echo. You don't need to NOT throw a ball just to make sure it doesn't echo.
