As someone that watches them, it's the yabs. /jidf/ has been demoralized as fuck since the Riro termination. The talents have had their fair share of hardships since that time too, multiple hiatus, increased PL activity and people not streaming in general. There's tons of rrats as to why, but I won't really discuss them.
Here's a QRD on the state of the talents
>PochiOn a guerrilla-only schedule, she streams when she feels like it.
>FuyoHad a bit of a hard time coping with the Riro yab (closest friend in Idol) but she is showing improvement and is over the worst of it.
>Rin, JunaDoing the same as always
>YukoShe is yabbing big time now. Hasn't been consistently streaming for a long while since she is on vacations with family allegedly. If you want the unhinged schizo qrd
>>66748156 but take it with a pinch of salt
>Katta NikkiThey had a bit of a rebellion against management some weeks ago over being neglected. They have since reached an agreement and back to normal.
>ConiDoing great, /corpo/ likes to shitpost about her preparing to leave because her PL is very active.
>Roca PokoDoing awesome, their fanbases are the happiest ones atm
>KaiThe most active of the PLs now. Like actually streaming on it.
>MomoHealth hiatus, hasn't been much of a consistent streamer since her debut though.
If I have to take a wild guess the root of the problems is management always biting off more than they can chew in order to keep the hype up. This leads them to neglect of issues with current talents that could have been solved before they were made public.
