Maybe I'm reading and listening to things out of context but these recent complaints about management reminded me of a little story.
Before Ichikara upgraded into all colors of the rainbow, it was a pretty black company. Some graduations were apparently due to disagreements with management and feeling fed up. Mito even discussed it.
https://www.youtube.com/watch?v=ZUbKHhKwx_o People would ask for things and they wouldn't really care. People got hit with bills for their designs despite the company being the one to pay for them. The most notorious graduation was Sasaki Saku, who wanted Nintendo permissions among other arguments with managers, and left because they wouldn't secure them, and why would she stream under a company that won't let her monetize the only thing she plays.
This inspired two livers, Chaika and Shiishii, into creating their own radio show to talk about how shitty management was, and the kicker was that Ichikara even allowed them to openly shittalk management, that's how little they cared. They'd have guests on and basically shittalk them all day but in a polite way. But, this radio show actually pushed Ichikara to change things for the better. Fans were agreeing with them left and right and Ichikara eventually buckled. Groups that weren't really allowed to collab with each other thanks to management (SEEDs and Gamers) got dissolved and all placed under the Nijisanji label leaving people free to collab, people who were forced to pay for their model got reimbursed, and they worked harder on game perms, even asking Sasaki if she wanted to return, and she did (with a funny video that also caused Belmond to skyrocket into public eye).
I'm not saying Hololive is anywhere close to the issues Ichikara used to have, and I don't understand the full context, but maybe it's a good thing that they're speaking out against things that management does that annoys them, maybe fans rallying behind their oshis can prove that some things that need to be changed are worth it.
