By contrast, how many conversations have you personally had with people working at a company believing a profitable action was firmly unethical, but felt forced to behave that way due to "business realities" or some other whitewashing?
On the second point: my experience is rather that there is quite a variance in what is considered moral vs immortal and that often drives different decisions (in the same place, some do certain things, other don't and certain experise/people might not be available for X therefore). I cannot say that I have come across many situations where people did something they considered firmly immoral but felt they needed to go along with it (trying to recall some). Yes, finding justifications happens, too, but that isn't necessarily whitewashing as people do disagree to surprising levels.
(Changed to moral vs immoral, because that was the starting point.)
