I'm not sure what's your point. Both Google and unique, information rich web sites provide great services and value for free, they deserve their advertising cut if some user is referred by them (CPC, CPA) or if they help promotion (CPM). MFA provides nothing, they just cheat the system, forcing themselves as useless extra middle men and polluting the web. Everybody would be happy to see them completely out of the search results, just like everybody would be happy not to receive email spam anymore. However, it's obviously a tough technical job for Google. As for sending users directly to other web sites... it's called "I'm feeling lucky". But most of the time, there is no way to know the perfect destination, so a list of search results is necessary.
