I don't mean they should make
papers by underrepresented groups open access. I mean they should make the papers
researchers need to read open access so that access to those papers isn't conditional on getting into a rich university, thus reducing the barriers to underrepresented groups and everyone else. By "their papers" I meant "the ACM's papers", not "the papers of young and female researchers".
It's extremely unfortunate that the ACM has been degraded into being a "publisher" rather than a learned society, and I agree that as long as they think of themselves that way, they will continue to obstruct progress and reproduce patterns of social and economic inequality in the way they are currently doing.
