It's simple: Weinstein made a lot of people rich and famous;  the price was dignity.  A lot of people willingly paid that price, I'm willing to believe a minority are genuinely naive. I'm not naive enough to think that a lot of people associated with Mr Weinstein didn't know exactly what the arrangement was, what the price was and what the payoff would be. Yeah, he's a disgusting scum bag, the people he made famous aren't much better, willingly went along and were handsomely paid. 

Hollywood is selling you a certain image, this image is not real. Oh, and Santa Claus doesn't exist, either.
