I think this is pretty fair on Google's part. How could you possibly figure out who owned content?<p>What if I published a book, it was copy-pasted in blogs, and then later I put it somewhere crawlable by Google? You certainly can't just say "first time we saw it, that's the proper owner". It would either require a massive amount of manual QA to get right (and even then, there are going to be interminable copyright battles), or have a super high error rate.<p>I think Google's best value is letting proper content owners easily find violators via normal searches, and let them deal with them via takedown notices or the court system -- which is where it should be done, not in a pseudo-court run by a Google who does not want what responsibility.
