Thanks for the answer.
On green OA I also said something passim at http://bjoern.brembs.net/2016/04/how-gold-open-access-may-make-things-worse/...

The first raises false optimism; the second might involve a lot of update editing. But they're workable.
Thoughts?
Personally I prefer template editing over mass editing, although duplicating links may be slightly noisy. I think one should just go the way which is most easily accepted in their wiki. Perhaps the same parameter that controls the "OA button" could also control the hiding of either DOI link? This would produce another incentive to mark DOIs as closed access, green OA or gold OA. In principle there is a mid way, i.e. a MediaWiki resolver (e.g. a special page, implemented in a new extension) which would handle all DOI links and redirect to either DOAI or DOI depending on what is available. Something similar exists for the wayback machine, but was not implemented yet in MediaWiki.
