Mike is quite correct, furthermore, amazon can't do anything about ads placed on google (not amazon) by someone other then themselves. Had amazon created the ad, they could have responded by taking it down.
Had they petitioned Google to remove the defamatory ad, Google may have done it as a violation of their terms of service, but even suing Google wouldn't have gotten anywhere.
Had they sued the person that actually placed the ad, then they could have gotten somewhere with the suit, though they would have to know who that was, they could have sued John Doe and subpoenaed Amazon for who owned that affiliate account.
What's funny is the affiliate probably didn't get any money from someone clicking those ads. Earlier this year Amazon changed their Affiliate program to state that ads placed on search results are not eligible for payment under the affiliate program.
An increase in the number of movies resulting in a decrease in the amount of time a movie is at the theater and a decrease in the amount of time the movie has to do well on PPV does not mean that piracy is the problem, in fact the problems you mention have absolutely nothing to do with piracy, but everything to do with an over-saturated marketplace.
It is true that there are far too many movies coming out, and competing for the same amount of screens, so they spend less time in theaters. Also IMAX is becoming a bigger and bigger fighting ground for movie placement as more and more movies are taking advantage of these larger formats.
This year there were two big fiascos that I can recall when it came to IMAX, "Star Trek" only having 2 weeks in IMAX despite huge demand for it to be on more screens, and Harry Potter and the Half Blood Prince not coming out on IMAX until weeks after it was out in normal theaters despite their special IMAX 3D offering, because of competition with Transformers already having leased the screens.
Actually studies show that during recessions attendance at movie theaters actually goes up. See when you can't afford to make big purchases for entertainment (like go on vacation, or buy a new video game console or going to theme parks), most people compensate by enjoying more "simple" pleasures, top of that list, going out to the movies. They may end up spending less money on concessions, but attendances at the theaters actually goes up during a recession.
Here's one of the many articles I found (in a google search just now saying that), note, I didn't write the article and don't necessarily agree with everything in it:
