I usually criticize Microsoft, but I am on their side in this case.
Why shouldn't Microsoft be using this kind of data? Google search result pages are part of the internet just like any other publicly available web site. Microsoft monitors what the users are clicking on Google and probably on Bing and other sites. So what? Monitoring users is not a new thing. It may be unethical and I may personally hate it, but almost everyone is doing it.
Google should stop whining about this and make their search result the best they can. If they had the best search engine, Bing could come close, but never overcome Google by just copying part of it.
