I skipped through it and it seems like nothing has changed with the allegations. I think the only right way of handling this situation is to double down and say "Yes, and so what?". No, "He is autistic and can't be held responsible". No "Those are big mistakes of him bla bla bla, but". These kind of people, will never be satisfied with what they get. They will try to break you and won't stop until you give them full submission. Stallman has made some mistakes in the past, but they are, firstly nothing mentioned in that "report" and secondly if anything it was conforming too much with the people, that pressured him into this situation. But all those mistakes are nothing compared to what the contributed to free as in freedom software and culture. The FSF and GNU are already a lost cause, but I think Stallman is one the few things or people, that prevent a complete SJW, super-politically-correct takeover of it.
I really hope those people fail with their project to remove Stallman.
