Google certainly wouldn't want what you've done to become a widespread practice.
They currently have the monopoly so don't need to change this bottom-line increasing tactic for at least another 5%-10% lost share in the search market. Flip-flopping constantly between boosting Adsense sites and dropping companies for more ad revenue is quite a decent plan, as they can blame it on the webmasters themselves for breaking "secret rules" only Google knows about (wink, wink, nudge, nudge).
They've certainly recovered their share price well after that massive drop. I don't think it was because Panda was brilliant for organic search ... do you? Since Panda, all I have seen over my 100+ websites and the hundreds more I work with is increased Google Ad spend and increase in spam/MFA rankings.
The best cover for all this, is Google has is Wikipedia. If Google didn't have Wikipedia in it's results, I think a lot of people would be trying Bing. Wikipedia is often the ONLY relevant non-advert, non-spam result.
