> He is surely very evidently mentally ill.
I don’t think that’s accurate or helpful.
I think he found himself in a situation that he could not cope with in a rational manner. I suspect that many people, myself included, would struggle in similar situations.
Occasionally a person can find themselves in a place where quitting is the best option for everyone involved, but the person at the centre is so dug in that they don’t even consider the possibility.
I think he has cultivated a group of yes-man to surround him and that he is so out of touch with non-WP reality that he thought he would be seen as a hero defending open-source ethics. He didn't account for the fact that everyone that he doesn't pay isn't under his spell, and that everyone saw the selfishness behind the heroism.
That is mental illness. It doesn't imply that a virus took hold of your brain cells. It can be inability to cope with the real world. I suspect most of us will go through it at some point in our lives.

There are, to me, abundant signs that he is severely burned out, dysregulated and irrational.
(In this statement, in other statements, in his actions that wilfully worsened his own case against WP Engine, in his blog posts etc.)
These are mental health issues. I have experienced many of them myself (I am indeed recovering from them now) and do not know what else you could possibly call them.
He is very evidently experiencing continuing poor mental health. I don't know why the board would say "leave of absence" if they were not themselves alluding to his health. He clearly needs a break from the thing he does for his own benefit.
I absolutely wish him well and hope he steps back and takes care of himself for a while; none of this is worth worse health.
