The argument that Google "scrapes and republishes" applies only to the Google cache. Whether that constitutes fair use is in the eye of the beholder, but the fact that Google lets Web publishers opt out of caching--and out of crawling, for that matter--does tend to weaken the argument that Google is forcing Web publishers to share content with Google and its users. (Copyright law attempts to protect both private interests and the public good, and if a court might well rule that the public good is best served by a search engine's right to cache pages--just as a U.S. court ruled that Google Images thumbnails were legal.)
In any case, this isn't a thread about copyright; it's about Webmasters being "under the Google mindshare spell" and whether "webmasters really want an Internet that is defined and dicated according to what is good for Google." It seems to me that, if the goal of this thread is to teach Webmasters to be more independent, those who are unhappy with Google should be encouraging members to use robots.txt and other tools to escape the Google yoke instead of perpetuating their "relationships" with (and dependence on) Google.
