There's a difference between things like selling standard VTuber merch and putting a talent front-and-center as the face of your company when it's clear she's burnt out and brainwormed over her numbers. When she's on break #40 and openly saying how she's suffering from burnout and her success has her rattled, that might not be the time to come to her with the next major event or corporate brand deal you want her to be a part of if you don't want to completely drive her away.
As fun as the Dodger's thing was, you know that shit didn't help matters on Gura's end. It's been discussed to death, so I'm not going to dredge it up again, but Gura's departure was very much on Cover. Holo fans can cope all they want about what "disagreements with management and company direction" actually means, but it's pretty clear to anyone listening, especially with how emotional she was, this was a case of "I didn't leave the company, the company left me." When your biggest name can walk out any time she wants, one would think you wouldn't want to accelerate her chances of doing that, and would attempt to accommodate her. It goes beyond her lack of streaming, because she's not even the only Holomem to start streaming less. Ayame's streaming schedule became a meme, after all.
tl;dr if you have a major talent in your roster freaking out about their status, and you accelerate that status, you're gonna drive them away, and it's on you.
