I'm sure by now, you've seen news of the allegations that Google has made against rival Bing, about Google's search results being copied. Google says that they can prove that Bing uses their search results –they have linked results to specifically garbled queries in Google, and then watched those same results show up for Bing searches. While there isn't a lot that Google can do--people who are in the know about these things say that Microsoft likely didn't break laws with this snafu--they do seem to be trying to deliberately embarrass their competitor. This really isn't that surprising to anyone, as much as Google and Microsoft have battled in the past. We expect the next move in this brawl to be that Microsoft will be caught shooting spitballs at Google, causing Google to reply with "Neener-neener" and blowing a raspberry.
Here's a plethora of links on this story, though they all pretty much say the same thing:
