Traditionally, academic publishers have covered their costs with subscription fees and paywalls. For some, the amount of profit some have been making might be regarded as profane. The drive towards open access for publicly funded research is disrupting this paradigm. Some publishers have introduced Article Processing Charge (APC) where the author pays a charge for their article to be published. The publisher makes their money by the APCs they receive.  Very quickly, it was pointed out that the APC system benefitted rich countries, and punished poorer countries. Rather than making scholarly publishing more democratic and open it created a class system that benefitted more wealthy countries and served to silence the voices of researchers without the same wealth.  Some publishers acted promptly to introduce concessions and supports for researchers from poor countries. This had a couple of obvious problems, middle income countries maybe more affluent than the poor but still be unable to afford the APC fees. The same is probably true of poorer institutions in affluent countries. Jurisdictions like France have responded to this challenge by directing that papers are published with Diamond Open Access publishers where there are no subscriptions or APC fees and their costs are covered by grants or philanthropic contributions.  Such an approach, would be genuinely open and egalitarian.
