How can they remove maintainers from their own projects? If my project is yawaramin/foobar, how can Ruby Central remove me as the mantainer from there?
This thread has probably run its course, and newer postings[1] have more information, but I'll respond anyway if it's helpful...

The official RubyGems projects in question were under a GitHub organizational account, not a single user's account. A subset of the maintainers had the "owner" flag on the org. One of those folks basically initiated the takeover. See [2] for a more detailed recounting.
That's a dumb move though, isn't it? The original maintainers will now just move their projects somewhere else, and the 'official' projects have now effectively been killed. This is a suicidal move for the Ruby ecosystem.
