>>55191460NTA, but you seem genuine in being frustrated, so I'll give you a genuine response.
It's justified to hate nijisanji as a company, even the most extreme rrats about their management have ended up true, but Its really not fair to assume that specific talents have to represent every single aspect of a vtuber under them. Pomu is very kind and sweet, and she herself has disproven rrats about nijisanji forcing things like having her vet her collab partners. Try to at least give hera chance, she's not too different from Lia.
As for the VOD wipes, i'm with you on being pissed off about it, but It isn't something sudden, seems like management has been slowly trying to scrub these VODs off the internet, most likely for since fishman want's her to change her image. Lia herself has talked about this pushback before, she definitely isn't responsible or even wants these VODs gone.
