If the guys got enough power and your career in the industry is over if you challenge it then well maybe are left uncomfortable and sad but stay quiet. seems loads of people knew the Weinstein stuff even if he didn't walk into a room grabbing T&A but no-body said anything.
Plenty of cases where the bloke with the power gets away with it even though people 'know'
It's also worth noting that this sort of power will not help you were there to be a tragic accident.
