Alicia, I do not wish to end up in a tit for tat over this but the three things you cite as 'evidence factored into decision-making' are precisely the three things that are discussed in the blog with substantial support for their lack of credibility.
1. The usage evidence on its own does not prove causation. 2. The causation evidence is based on a 2012 study that has no validity and the methodology of which has been soundly rebuked. If the dire predictions of the 2006 study had come to fruition in the ensuing nine year period then this would itself be the evidence rather than the original study. 3. This has nothing to do with green open access and everything to do with the gold open access model versus a subscription model - an important but different debate.
