It's an interesting question. As I said, many of my speaking notes on that point come to me from CAUT, national level. Their framing of the issue is that works that have already been funded through public dollars ought to be made available to the public that paid for them.
It goes hand in hand, in a way, with muzzling of federal scientists. The idea of open government, open access, open data, I think, is the inspiration for that idea. The public should have access to the works that they helped fund.
