But that is different than saying the prioritization of this as a "problem" is or is not affected by AdSense revenue. What we, as a bunch of highly technical people, see as a problem, Google's ranking decisions sees as, at best neutral and at worst, a positive.
It may not affect ranking (and I do believe that), but I would certainly be willing to bet it affects them (and similar sites than aren't AdSense-based) not being de-ranked.
I work in Search Quality at Google, and this is stated policy. Revenue from any source (the ads on the results page included) is not a metric used to make ranking launch decisions.
If me saying so isn't enough evidence for you, consider that it makes sense. Google knows that losing the lead in search would be much more damaging then shutting down all of AdSense.
