I don’t see it likely that it will be changed back. If the SDMB, the most conservative place on the planet (can’t even stand images), won’t listen to the people telling them that multiquote by default is annoying, I don’t expect Google to listen to people. What they are doing isn’t any different from what they were doing before, from a legal standpoint. That, and I’ve never seen Google change anything back.
Actually a few years back they did the same thing with the image search, not displaying the image size, URL and description unless you hover the mouse pointer over; there was an uproar and they changed it back.
