Why not use copyright a different way to achieve a goal of openness, and still bring in some cash? Have all the articles free to read. Charge money to cite the articles in other academic papers. You'd have to invest in lawyers to go after people that try to screw you (plagiarizing without citation), but everyone gets to read and learn, it creates a barrier to entry for crap papers that mean nothing, and you can keep it cheap enough to not have it be a huge burden on actual researchers.I'm not a copyright lawyer...I don't know that this would work, but it's a decent idea, I think.
