Researchers are already paying to get their articles published. Given how much journal subscription costs, that cost is a fraction of the taxpayer money that is spent buying back the articles for the university libraries the same researchers use.
Although I am friends with David (the author of this blog post), I do not agree that open access is fundamentally the wrong model, but his argument is not without merit.
I'd guess that a "teaching university" would have nearly the same need for access (if the teaching is any good), but much less need for submission, compared to a "research university", so the teaching university should benefit from shifting cost from access to submission.
