Thats the case for any company that goes public. If you think Google still lives by the "search all the worlds content" mantra boy you have it coming to you. Google isn't a search company anymore, they're a marketing company leveraging search in its many aspects to advertise to you.
Google's network isn't impervious to fraud either. I see MANY sites - illegal, embarasing and even immoral that have adsense on them.
yes, yahoo can do a lot to clean up its act but its far from being alone in supporting a corrupt content network that is ripe with abuse across the board.
More people scam adsense alone and Google profits from it then anyone could care to imagine simply because google is better at being a black box and believe it or not Yahoo is more transparent.
