They are a corporation so we definitely shouldn’t take them on their word I just don’t see much value in coming up with imaginary abuse “just in case”. You don’t have to trust to not make up stuff without evidence.

As for their leverage… it sure is there to some extent but it’s not absolute. As much draw as Hololive as a brand has, viewers stay for specific talents. Every time one of them leaves (whether it’s graduation or termination) they bring some chunk of their audience with them - it’s not like they are completely dependent on the company.

Edit: As for actual abuse, that was the case with Mel and her first manager if I recall correctly. Dude was fired and they changed their rules to better protect the talents after that. That was the early days, back when they neither knew what they were doing yet nor had a proper staff to deal with such problems. It’s still a screw up, but apparently they did learn from it.
