There already exist any number of places that show more, e.g. thumbnail images of a web page.
What you are advocating (based on what Brett posted) goes far beyond simply returning search results.
Would you advocate for my right to allow my users to drill down into your site's pages via AJAX on my monetized site? I think not. At that point I suspect you would think of me as a scraper and would be blocking my access to your server. You might even be initiating legal proceedings against me for copyright infringement!
Of course, I would argue that I was simply providing my users a service and a more pleasant user experience.
US Copyright law looks at 4 criteria for fair use
(1) the purpose and character of the use, including whether such use is of a commercial nature or is for nonprofit educational purposes;
(2) the nature of the copyrighted work;
(3) the amount and substantiality of the portion used in relation to the copyrighted work as a whole; and
(4) the effect of the use upon the potential market for or value of the copyrighted work.
Within that context, how would you defend G's right to display substantial portions of your material on their monetized (i.e. commercial) pages?
