I suppose the arrogance comes from the fact that they are so so much better than other PPC engines. I have tried third level PPC engines and find rampant click fraud ( mostly bots). I would estimate that I have been defrauded by upto 80% from these so called search engines. MSN and Yahoo are o.k., but frankly I never did try to estimate how much click fraud these guys tolerate, because, I hardly get any traffic from them!
