I don't like this legislation, or any other legislation that increases copyright restrictions (especially in favor of clueless dinosaurs), but I also resent the hypocritical way in which Google pretends it's protesting this as a public service.
Google is only interested in what makes money for Google, and it has lost any credibility when it comes to looking out for the public's interest (or "do no evil" in general) a long time ago.
Their campaign should be called "Defend our profit margins", Google is no better than the publishers pushing in favor of this legislation, their interest just accidentally happen to coincide with ours.
