Well, I don't think his name could be removed from any of the show's historic documentation, including IBDB, etc. But if his fortunes worsen, as it seems they surely must, I can imagine a scenario where his name becomes seen as anathema to the ticket-buying public. Presumably, he would remain a silent partner in the shows. This is an imperfect comparison, but there's the case of The Current War, a film starring Benedict Cumberbatch and Michael Shannon, produced by Harvey Weinstein. It got shelved in 2017 when the Weinstein scandal blew up. It was eventually acquired by another releasing company and Weinstein's name was played down if it was mentioned at all.
