I'm in his (extremely long) black list, but I really admire the project and use GrapheneOS. And I would prefer to keep the drama if that helps the quality to be high.
He just bans you from all their chats, github projects, etc.
Other people got banned just for being in CalyxOS chat.
To his credit he is definitely serious about any constructive criticism. I've been unhappy about lack of NLP and they've added an awesome NLP support mechanism into GOS. After that I switched to GOS completely.
After his rants I told him that as an asperger I suspect that he might be on the spectrum and it might help to dig into that direction. I'm quiet surprised that now he identifies himself as an autist. That might be just a coincidence though.
If he is lonely I would advice him to get a dog and a partner.
