Well it's interesting to see an article that pushes the subject from the other side, but it still reads to me like a contrarian work published in order to drive traffic to the site from wikipedia links and whatnot about a controversial subject.
Some small points are made, but overall it doesn't especially provide any sway on any angles beyond those that ubi themselves are already trying to push. It's more like "well it works for my situation, so is it that bad really?" type fare. Also, very US centric when the DRM itself is pushed worldwide as a one-size-fits-all type deal.
A mildly interesting read, but does not convincingly address the genuine issues.
