I would add a "3." that Google has less incentive than they used to to fix it. If they can supply enough relevant ads,"rich snippets", shopping widgets, or links to content they pulled from wikipedia (that keeps you surfing google-owned properties)...the organic search results don't matter. Actually, if the organic results are low quality, then maybe you're more likely to use the content above. So the organic content optimal quality is just "better than Bing", but worse than the ads.
