Fund Gold OA Only AFTER Mandating Green OA, Not INSTEAD

What universities, funders, researchers and research itself need, urgently, is Green OA mandates, not Gold OA Compacts. Mandate Green OA first, and then compact to do whatever you like with your spare cash. But on no account commit to spending it pre-emptively on funding Gold OA instead of mandating Green OA -- not if OA is your goal, rather than something else.
