I think that the strongest evidence for this is that Hina is still listed as an active talent. Despite being as spotty or more than Clara. Additionally both Saya and Memory, both now Phase World Citizens, reported that management tried to keep them on. That the fish is more than willing to let people go inactive and that makes a certain amount of sense. If they aren't streaming then they aren't generating any profit for him but neither are they getting anything nor are they generating merch. Aside from sunk costs, it costs the company nothing to simply keep them on the roster until a day comes that they decide to get back into the game and start earning again and if that's the case?
Then why toss someone off on the side of the road and generate all of that heartache and ill will?
