Okay, controversial cynical opinion here: from where I'm standing, Eugen didn't really intend to shut down registrations for the purpose of encouraging federation. It's mainly because the backlog is on fire and the servers are having trouble scaling, and it's a happy coincidence that it does that.
I don't think he would've done it if he didn't need to, so no virtue points there imo. Utility points, sure.
And I could be totally off-base here.
