Agreeing with most of the other comments here that this discussion needs more context which we don't have...
If the request for additional access controls/access cleanup came from one of the Ruby Central funders, could we not know who that was and what exactly their ask consisted of? I am interested in knowing their side of the story, and what the motivation was. (But in general, cutting off long-time maintainers' access seems like a bad choice - as presumably they have long since proven their good will toward the ruby community as shepherds of these projects.)
