I don't think this is a question of someone doing "sketchy" things. Its a question of someone in the room questioning a morally questionable action, being implemented by a part of the organization as a whole. Quiting over it, or whatever likely doesn't even have an effect. Someone on the team required to implement it is going to follow the bosses orders. This appears to have happened a few times with members of the US president's cabinet over the past few years.

So, its more a "stay and fight" or "get rolled over and threaten/quit" decision. I'm betting most people just weigh the monthly mortgage payment against that and they raise the issue, but it doesn't get pushed beyond the discussion phase. If this goes on long enough, they switch jobs, or they become that person that just keeps their head down and do what they are told.
