We are better off if we ignore what Google is saying and follow one thing: Google wants more money for Google. When we make this assumption, everything Google does makes sense. Deception and doublespeak are logical and expected rather than shocking and upsetting.
When it comes to scale, as pointed out with Groupon, all of these rules go out the window. If you look at the biggest advertisers, replace their account with one with no history and the brand "Geico" with "SEOBook auto insurance" and the campaign will simply not run. You are spam. In some cases larger advertisers are able to run ads which are clearly deceptive and go against guidelines which they actively enforce on smaller advertisers. I have a strong suspicion now that this is in fact institutionalized in Google's rating process rather than any employee going out of their way to overturn some sort of penalty.
