Google can do what it wants since they don't depend on anyone else's rules for their traffic and have few real competitors.They depend on the public having faith in their products. They are not too big to fail. Take away confidence and they loose everything. There are many waiting to take their place.
Emulating Google is destructive.As discussed above, that statement doesn't make sense unless you operate a search engine.
Google dislikes and penalizes affiliate sitesThat depends on what your definition of "affiliate sites" is. I manage several sites that publish affiliate links and none of them are penalized.
...sites with lots of above-the-fold advertisingYes and thankfully so. That's just bad webmastering to put a lot of ads above the fold. Nothing makes me hit the back-button faster.
Yet, Google is an affiliate site with lots of above-the-fold advertisingI wouldn't call Google an affiliate site. They own a company called Adsense that sells advertising. That's not what typically is seen as an affiliate. However I agree, they put as many as 3 or 4 Adsense ads at the top of some SERP. I think most everyone dislikes that.
