Thanks Jonathan.
Max, just a question. Where were you told that "the paper was under the OA mandate but indicated that funds were not available to pay for OA publishing."? This sounds like something that may need some additional thought from Grantmaking. I looked for a discussion on the WGI talk page but that discussion isn't there. I'm too stretched with other commitments to escalate this issue myself, but if the combination of issues is as described in this email thread then this issue might be good for Grantmaking to consider in light of the bigger picture.
