To add, did Ruby Central consider going to the community and asking for funding so they wouldn’t have to be beholden to one or a small group of key funders? If they were at risk of shutting down without this funding source I think the community might have rallied around them so they could make more independent decisions in the best interests of the community.
This is not to say that they didn’t act in the best interests of the community by tightening security, but an organization of this nature should be able to act more independently.
