Will this cause people who haven't heard of Bing to know about it? Yes. Will the headline "Google claims Bing is copying its search results" leave a good first impression on those users? Probably not. Whether or not people perceive the claim as accurate or complaining or whatever, first impressions are still powerful. If the first time you hear of Bing is the accusation that they're copying someone else's results (true or not), that's probably not a first impression you would want people to be left with if you were Microsoft. Chances are, people are going to read this as "My trusted search provider accuses unknown search provider created by the same people as Windows Vista of stealing its results".
