Something really scary is going on in Germany
Here are a few points to consider:1) The notion that the systematic clipping of one or two sentences from every news story you can find on the Internet for the purpose of selling ads is "fair use" is totally absurd.2) The "robots.txt" argument misses the point because the publishers never gave permission to use their content, so the presence of an "opt-out" mechanism is irrelevant. The mechanism must be "opt-in", i.e., Google must ask to use their content.3)If we believe that intellectual property has become an obsolete concept altogether, we should be prepared to accept all of the consequences of this, e.g., a site might pop up using a new TLD that accepts a search query from a client, passes it on to Google using a spoofed IPv6 address, and passes the result back to the client. We also shouldn't care about plagiarism, trademark infringement, etc., because the Internet has clearly made these concepts obsolete and laws related to them unenforceable.
