This is a coordination problem. There are some efforts in this direction; for example, the researchers who led the Elsevier boycott http://thecostofknowledge.com/ http://thecostofknowledge.com/ started a free open-access journal https://discreteanalysisjournal.com/about https://discreteanalysisjournal.com/about in which I'm proud to have a paper accepted.
