If you haven't met RMS in person, it's hard to understand what a raging asshole he is. Frankly I'm surprised it has taken this long for him to be called to account for his behavior.
That does not remotely justify ousting him on the basis of lies, which is what happened before. If you do that, it's really hard to argue that the correct course is anything but reversing the actions you took that were driven by lies.
He was staying for a few days at a colleagues house and even thought he seems to have some weird preferences I didn't really hear anything negative about him. Seems to be a nice guy to be honest and I trust in my colleagues ability to be a good judge of character. (Didn't meet RMS myself so can't attest for him myself)
