The February issue of IP Law & Business has a couple of interesting pieces (free registration required): "Pulling Back the Covers" (Google is dragging the book world online. Will the publishing industry make the leap with its copyrights intact?), and "Meet the dotCommunist" (about Eben Moglen: "This Columbia law professor believes all intellectual property should be abolished. So, how did he get the backing of some of the biggest IT companies in the world?").
It further illustrates my contention that most opponents of IP are, unfortunately, either unprincipled (read: utilitarian) and/or anti-capitalism. But there is a principled, pro-property rights opposition to IP. More IP resources here.
