It's an interesting OP in the sense that it shows that some big players are trying to brew up trouble for Google using antitrust mechanisms. The screed itself is not very informative (it's an attack piece by a lawyer for the other side). Now, I would like to understand who "the other side" really is, and to get an evaluation of what they hope to gain and what their chances are. It doesn't seem that the other side is competing search engines, probably more like competing advertisers.
