To sum up
Bing isn't stealing Google's results. It's just taking account of something sensible in working out its results. And what it takes account of - what we click on when we search - belongs to us as users, not Google.
Even when Google has found this makes a difference, it has demonstrated this only in cases involving search terms that no one actually searches for - and even then in only 9 per cent of these made-up searches.
Overall, Google is making a massive fuss over something for its own reasons. Bing has done nothing wrong.
