If publishers play hardball, no researcher will ever work for them as authors, referees or editors.
Or they come down to more reasonable prices and perhaps reduce their 40% profits to ones in line with other industries?
No one really wants to criticise anyone and every work should be fairly rewarded. It is the unfair part that people are objecting to.
Also, it's less the price but how the money is (not) redistributed, I thought.
