You might dig James Boyle. I haven't read "The Public Domain" (book by him) yet, but I have read the IP Caselaw textbook he coauthored. It's really meant to be a textbook for law students, not a treatise on anticapitalism, so it mostly doesn't go into the kind of stuff in this article, but it does have excerpts from The Public Domain (which is a lot more about the kind of stuff in Nesbitt's blog post) throughout and the final chapter in particular is very much on that topic.
