Is this true within an academic publishing context? First copy costs remain substantially high: editing, review, typesetting, server and band with costs, marketing etc. are still part of a digital only model. One thing that is important to explore though is what these first copy costs consist off in a digital context, to explore from there what the profit margin is that publishers put on top (plus cost for printing etc.). This could lead to the development of perhaps a more fair and transparent system based on actual costs.

This doesn't sound like a problem to me. Individual research communities should be able to adopt an OA style that works for them. I've never thought it realistic that the sciences and humanities will pick the same kind of OA, it's never been clear to me why it even needs to be the same kind, but [deity] do we waste a lot of breath and text talking about this.

My paper is actually open access at the original journal site, here: https://asis.org/Bulletin/Apr-13/AprMay13_Mounce.html
