Earlier quoted context omitted.
It's embarrassing for Google to complain about this. You FINALLY get a little competition on your turf and you try to make some big issue that, as a market leader, the product you produce is being watched, analyzed and in some ways incorporated by your competitor. There is no victim here. They are not taking your 1st result and copying it. They are taking the result the user clicked. Obviously you didn't predict that…
Just because you are big, doesn't prohibit you from exposing issues. We really don't know how much value Bing puts on clicks made on Google. Perhaps a lot? What's the Google's official stand on this?
If the case described above were true, then all Google has done here is to make inconclusive accusations and use the occasion to highlight its own dominance over search.
It seems to me this is just a cheap and slightly seedy PR stunt.
