[Update 2015-09-19: since writing this, I notice my open access article has now been unpaywalled at Wiley’s site. No-one from Wiley has reached out to me to explain how, why, or when this happened. No compensation has been offered, nor any apology. I note that all the other articles in the special section, which should also be open access (CC BY) are still on sale, behind a paywall.
