Or something's wrong with their entire line of reasoning.
I can see it wrt press releases, where the intent of the original writer was to have their work republished all over the place, and readers might as well see it in its most authoritative home (that's probably good for the brand as well). But aside from that case, I don't see it.
What I can't figure out is any reason why Google would WANT to:
(a) index multiple copies of the same thing (except maybe in the case of press releases, but I'm not sure I even see the point there)
(b) ever, EVER rank the duplicate above the original
But they must have a reason to want this because their solution - handling who knows how many DCMA requests a day - is likely more expensive than tweaking the algo to do whatever Bing's doing to plagiarists.
