I don't see how people can be mad at PC in general or Fish over anything here, Allah forgive me for even saying this. Sure, we don't have Yuri's side of things, but this isn't a Zaion situation where one side just piles on random shit and buries the other without them being able to reply, hell, Fishman is literally telling people to stop spreading rrats about her in the discord and let it go for her sake. Fishman also probably paid out of pocket for Yuri's second model, and it was made while she was working for PC, by what logic is it hers? Even if she did get it, I doubt she was going to use it, seeing how hard she went out of her way to delete any Yuri content other than the one VOD she presumably left up to create drama.
Getting assmad and deleting all your VODs and videos, out of spite or as some kind of leverage or whatever reason, really, without giving your fans any warning or time to save them is a dick move, by the way.
