While I agree that this legislation will be ineffective in fighting piracy, I don't think Google is concerned about the effects of piracy. This would seriously threaten any site that deals with legally questionable material. Instead of dealing with a DMCA notice, now they are threatening with the loss of their site. And it's not like you have to try to infringe when dealing with user submitted content. In the Google vs Viacom lawsuits, the Viacom legal team brought up videos submitted by Viacom Marketing employees as evidence of infringement.
