I'm sure you can find a way to get a hold of him and see if he will recommend his attorney and legal approach. If his attorney and applied approach turns out to be totally unfeasible, then you know that somebody else is potentially supporting Richie. You don't really have anything to lose.
And maybe I'm wrong, but Richie seems to be a pretty straight shooter to me. He's not exactly a "glamorous" ThemTuber so I would be pretty damn surprised if he's being backed by someone else. He seems pretty no muss, no fuss.
