There is some more context on a post[1] in /r/ruby, including the fact that the maintainers and others had been working on a proposal[2] for a formalized organizational governance structure as recently as yesterday. The latter also adds some context into Mike McQuaid's involvement: the proposal was influenced by the structure put in place by the Homebrew project.
