I've never written a line of Ruby in my life so this is coming from an outsiders perspective, but after this I don't know how anyone ever works with these people again. I would think the entire community would start finding ways to migrate away. Presumably those repos can be forked, and it sounds like a new source of Gems can be hosted. I doubt it would be easy by any stretch of the imagination, but essentially this entire leadership team just showed themselves to be entirely untrustworthy.
