My interest in seeing Bette Midler in Mame is sub-zero, but I do get what you're asking. If Rudin produced something I did want to see, would I go?
Very possibly. Depending on the price, of course. Or not. I'm not sure at this point.
Who knows which producers are nice and which are horrible people? And how many of the people working on other shows enabled Rudin? Should we avoid their shows too? And how many people on the Rudin show need to make a living, feed their kids, whatever? Boycotts can have serious collateral damage.
I'm never sure where to draw the line. I wouldn't go to Chick-Fi-Let or the Salvation Army because my money would go to fighting against my own rights. I don't watch Woody Allen's movies anymore, because they make me feel skeevy, even though I have no idea what exactly he is and isn't guilty of. But I do shop at Amazon, so I'm far from pure.
I think a problem I have with the Rudin story is all the grown-ups who put up with his treatment. I've quit jobs with bosses who were far less awful. On the other hand, I was in a field where there were other jobs, which isn't necessarily true in theatre, so my situation wasn't the same. In fact, I imagine there are people who would work for Rudin right now, because a foot in the door can be so so so valuable.
A long-winded way to say "I don't know," but there you have it.
