I doubt they'll get involved. The mainstream media really doesn't give two shits about Vietnamese moving drawings and generally seems to avoid it. Like most countries, the US population doesn't care quite as much about things that aren't from here in a general sense, and the loony left doesn't fetishize Japan like they do with other ethnic groups. They're just not brown enough.
However, I think it's getting to a point where it might not matter because it's going to be too hard to spin unless you take the law twitter approach of completely burying your head in the sand. If BHBH does have some key affidavits that torpedo some of the testimony from the defendants or even just outright exposes their tortious interference then they aren't going to want to pick up a lost cause. The last thing they would want is another #metoo story that explodes in their face and turns out to be bullshit. Far better to sweep it under the rug and pretend it never happened.
