> Being uncompromising in your politics and values is hardly authoritarian

In general, yes, but in this particular case it is clearly "I am the Law!" case - he's being authoritarian. And your next two sentences pretty much confirm that, even if you dismiss it with "they knew he was an authoritarian when they joined" and "he's been an authoritarian for a long time". Maybe true, but doesn't make it better.

I don't remember confirming his authoritarianism, I'm not sure why you think that's what I'm doing. If you think any exercise of rightful power is authoritarian than that's a childish definition and waters down what actual authoritarianism is.

"RMS runs the ship", "RMS has shot down things he didn't like before".

> If you think any exercise of rightful power is authoritarian

No, not any - this particular one, and in general one that is done "because I want it so, and your opinion doesn't matter because I decide here".
