>>109668421Honestly the Reimu shit was the worst thing for him. After he cheated on her she dropped dox on him and basically destroyed his whole reputation. That caused him to have a series of mental breakdowns. Even recently it came back to haunt him with the Bari leaks where he's portrayed as being a cheating scumbag.
Also I've seen posts from femanons saying he's very difficult to watch because of how disgusting he is in general and loves burping, farting type jokes. Without his ASMR spam there's no reason to watch him.
It's not just him though, the branch in general has totally imploded in terms of audience. The girls lost their viewers by doing a series of catastrophic "owning the incels" stunts and chasing relationships with the guys. The guys ruined their fandom by generally being drama queens and emotionally fragile.
