I encourage him to continue to talk about his journey, every last disturbing bit of it. He still believes that he is owed subscriber support and donations, and that those who contribute to his "wages" need to back off and let him be himself.
I'm wondering how many of his remaining supporters are thinking the way that commenter is- how can they recommend his channel now? If this isn't the last straw, what exactly are they recommending to people? At what point do you decide that he has crossed enough lines? What else does he have to do, for you to decide that maybe he isn't the person you want representing you?
