The fucking correct thing to do. A formal public apology should be the bear minimum for them to even be seen acting around a group that harassed multiple talents for months, caused one graduation, and the destruction of an entire branch of the company. Concernfagging has an implication that nothing is really that big of a concern. I dunno, I recall dozens of members being bot spammed, art tags being fucked with, the death threats, the gore posting, having people like Flare and Fubuki having to explain that they had no intention to abandon Coco over chinks and getting shit on for it. This isn't even discussing the shitshow internally with how they handled the problem.
Ignoring all of this, it's not like China's netizens have had some massive shift in how they act, the moment they think you said something negative about them or China, you're going to have schitzo's until you appease and grovel towards them enough and even then it might not be enough. It's a fucking trope at this point for gods sake. It's a terrible choice because at the end of the day, some schitzo is going to get offended, and decide to rev up a new hate campaign and it'll be the talents who get the blunt of it. And for what? Bilibilii money? Fuck that.
Shut the fuck up you don't know what you're talking about.
