An interesting (and undoubtedly smart) move by Google. This is part of their campaign to at least create the image that they are cooperating with the content industry and not “enabling piracy” as rights holders say. I personally disagree that a search engine actually enables piracy by simply reporting results, but rights holders seem to be getting at least some traction in Congress. As such, Google sees it as smart to try to stay ahead of potential legislation and, possibly, to argue that new proposed legislation which would otherwise effect it is not really necessary.
The cat and mouse game continues!
