Quoting from the piece: "The costs of research publishing can be much lower than people think,” agrees Peter Binfield, co-founder of one of the newest open-access journals, PeerJ, and formerly a publisher at PLoS. But publishers of subscription journals insist that such views are misguided — born of a failure to appreciate the value they add to the papers they publish, and to the research community as a whole. They say that their commercial operations are in fact quite efficient, so that if a switch to open-access publishing led scientists to drive down fees by choosing cheaper journals, it would undermine important values such as editorial quality." There's also a comment piece by three open access advocates setting out what they think needs to happen next to push forward the movement as well as a piece arguing that "Objections to the Creative Commons attribution license are straw men raised by parties who want open access to be as closed as possible."
