The other clear distinction to make here is that it isn't exactly Google's fight since the content that is being targeted is merely being indexed by Google not created by Google. So logically it is the content owners/creator (website owners) who should be standing up to this kind of action. Unfortunately such fights are often extremely lopsided (small publisher vs. huge corporation), so people expect Google to step in to help because it is tangentially involved, but most of the time it is simply not practical.
