Josh is utterly obsessed with keeping his own userbase on a constant state of attrition and neurosis, because that's the only way he can even get away with his daily manchild screeds about "muh freeze peach" "muh debanking" "muh anime" "muh cheese" and so on. If the users were allowed any kind of respite, soon there would be quasi-universal agreement that Josh - and his micro-clique - are useless, unlikable hacks and aren't as essential as they like to think they are.
It makes sense why DM chains are even a thing. All Josh does is just act like an unhinged toddler or create unnecessary drama everywhere he goes because of his various personality disorders. The concept of people just wanting to relax and chat normally with one another is absolutely foreign to him.
