Not Google's fault...
Danny Aerts, CEO of .SE TLD in an article at IDG say that Google by their adsense product is digging its own grave. In reality this is not Googles fault. The fault is with all the TLDs that allow tasting, fast-flux and other fast changing registration mechanisms. Specifically tasting. Something I know Danny is against. Domains should be used properly, but to some degree that will always be people that want to use the fact people guess and misspell domain names. That Google then is making money on ads, well, that is not really their fault.
I just hope Danny and .SE remember this article and other statements they have made regarding tasting and fast flux related mechanisms when .SE is creating new policies for the .SE TLD.
