Whistle blowing policies are not worth the paper on which it's written. Equally worth are HR grievance policies (of all kinds). The sure outcome of invoking either is that (1) you'll lose your job (2) you'll never find a job again.
One difference with blowing the whistle, though, is that it'll lead to your death: you'll be killed if you're lucky. If not, you'll lead a painful life of professional and social ostracization, which will eventually lead to suicide. So, choose your poison.
I think there's some degree of truth to this, but that you're overstating it.
A realistic takehome message is that sometimes it's best to just walk away.
Sometimes you can even ask for help with the walking away gracefully.
(When asking for help leaving, from within the organization... I suspect you'll need either trustworthy institutional mechanisms for that, or to find one or more individuals who are smart, of good character, and who have the ability to help. Don't ask the wrong person for help.)
