I don't think Google wants to hurt anyone. Google just wants to return the best search results (in the opinion of searcher, not the webmaster/ owner). That's essential to their longterm survival (forget short-term profitability).
Think about it, since most 'content farms' were emblazoned in adsense, what financial benefit would Google have from attacking them? They were great for Google; they converted natural unpaying (for Google) listings into ones where often Google earned on the next click!
