Unfortunately, not many organizations will have the aligned incentives. If businesses that conduct potentially dangerous operations, were required to get an insurance, then insurance companies would have incentive to pay money to the whistleblower vs paying out a much larger claim down the line.
Corporations are created by and controlled by governments. Maybe stricter laws and heightened enforcement?

Conspiracy is criminal collaboration. It is not "falsehood."
If you need this, your culture is beyond lost and your management team will sabotage it to ensure they maintain autocratic control.

Every one of these companies either was or had become quite autocratic and bureaucratic.

It's pretty easy to see it in action, and all it takes to beat it is a call from the CEO or someone above the manager of an employee that seems to be holding back in a meeting or in a email. "Fran, you seemed to be holding back. You are the kind of person that I count on to let me know what is really happening. Why were you holding back?" usually results in "My boss will fire me if I tell anyone"... And what comes after this is exactly what the CEO needs to know.
