Honestly, if he keeps getting into petty drama with random tubers thanks to his crippling narcissism, it's not too far fetched that he'd end up losing most of his viewers, specially with how fucking retarded slop all his videos have become lately and quite literally the only talent at the company fucking off to newer pastures with better work conditions.
I personally don't have anything bad about the remaining presenters (except the redhead cameraman faggot), but compared to the ones that fucked off, they're basically a charisma black hole, and at the end of the day that'll show up on the view metrics and retention over time.
