Well, they don't want to show any restraint, AFAIK. The saga of clueless/greedy/whatever authors against technology is much larger than this particular case, e.g. just two days ago it was reported that the Author's Guild is seeking $2B from Google for book scanning and making snippets available, that's $750 for each book! Many authors back these efforts.
My (optimistic) feeling is that a small circle of businesses is brainwashing the authors, citing music piracy and the "success" of RIAA in suing pirates and the authors are taking the bait.
Most books don't break even. Also, many books scanned by google are not easily available, out of print, or out of copyright, so I would be very surprised if google is costing authors anything like $750 per book. In fact I would suspect, if anything, it will help drive book sales.
The other thing that crossed my mind is that Google is still making use of the books - I doubt that just making them available publicly is part of their plan. If they're also licensing them for spelling correction and translation, how does that affect the pricing?
