The overall sentiment seems to be bad. It's a few steps up from Niji-ID, but if I told you six months ago that I thought most of Niji ex-ID would be gone in a year would that have been unreasonable? Not really. Millie and Enna being super honest on stream that morale is low and Niji has been taking Ls. Mysta obviously not giving a fuck, shit talking the company, etc well before his grad was announced. The "covid" tweets where Luxiem basically call Niji liars for using the covid excuse to cancel the EN concert.
That said there's an insider who has been leaking things on /vt/. They accurately called the Nina graduation and date, then accurately called Mysta and the date while saying many more were waiting to see how things went. The problem is they're not using a tripcode, so there are dozens of fake leaks about too. One that people thought was the same person involved Shu, who coincidentally has been checked out in a way similar to Mysta. Selen is also talked about a lot because she's been more distant from other livers, I would recommend watching her conversation with Nina on Nina's graduation stream.
Someone else also leaked the new wave designs, and two recruits in that new wave got fired before debut and one wasn't replaced. Later it developed that a vtuber called Arvun had told too many friends he had gotten in and they had spread info around, causing his firing, with some rumors that he hadn't been happy with the contract or management anyway and had possibly done some revenge leaking.
The Zaion/Sayu situation was also mishandled badly with the company coming off as extremely petty, revealing things like stealth suspensions disguised as breaks.
tl;dr Genuine leaks and genuine low morale making it a den of rumors.
