Niji doesn't even properly implement the NDAs it has out, there are multiple former talents out there who are not bound by one at this very moment. They are not going to tank their future in v-tubing to shit on Niji, and even if they did they do not have the full picture. It'd take multiple members of upper management leaking things or a full-scale investigation on the level of Enron to figure out what the fuck actually went on at Niji.
As much as I'd love to see it, it's just not going to happen.
