As fun as it is to doompost about antis, Chinese dick-sucking, corporate back-stabbing, and casting couches (get real), I think she just got fed up with Hololive and is gonna go independent.
Someone mentioned it earlier, but I think the "Fuck Yagoo" comments at the end of the Calli meme review were genuine. Not some big blow up, but she was expressing her frustration with Hololive's bureaucracy.
Think about it from Coco's perspective: What is she getting from Hololive? She's a top earner, yet she can't collab with EN. She can't do her AsaCoco segments. She doesn't get included in HoloGra. They can't even handle the spam competently (They actually bungled it even worse).
As an indie, she can do whatever content she wants. She doesn't get to collab with Hololive anymore, but can collab with just about anyone else. She'll lose some revenue (with Hololive out of the picture, maybe not), but who cares? Having the freedom seems like a price worth paying.
That's why the past few months she's been a bit more active as Kson. Testing the waters and laying the ground work to see if she could make the jump.
Hololive relaxing their restrictions on Coco collabing was their attempt to keep her around, but I think it was too little too late.
For many of the girls, going indie would be a death sentence into obscurity (looking at you, Calli), but in Coco's particular case I think it's the right move.
