Yeah, unfortunately many reactions/discussions of the article often strike me as having learned nothing from the article, but I think the article itself is excellent & worth reading & thinking about in relation to one's own communities.

I find the norms around making fanworks based on fanworks to be fascinating because there's (to me) an inherent contradiction with the position "we make fanworks based on canon without permission but you can make fanworks without fanworks without permission" that never-the-less comes out of a deeply community centric concern. It's one of the most fascinating set of contradictory norms to me -- cool to hear that you guys touched on it!
