I think it's about content: Google has transformed the webs' spam gardens by promoting crap sites. Because Google pushed low substance sites high in their search results, this created a vicious cycle where sites were rewarded for creating mass volumes of inane 'content', which has now become a huge percentage of the web Google isn't just an observer to the system, search results impact the ecosystem as a whole. A complicated environment is something that is challenging to test and to predict, although that is what Google internally is geared for. Personally I'm also annoyed by Google's Adsense policies that emphasize inane content: (They without warning blocked me for a post of a painting that included a nude figure).
