I see what you're saying here but it might not be so simple. These types of countries are all competing doing all kinds of evil stuff to do so. All or most would have to be hit with whistleblowing & often for what you say to matter. What we've seen is large scale whistleblowing in some countries but not others. A few of those crying "Foul!" are almost certainly doing equivalent or worse but benefit from being the moral, high ground.

The result: a whistleblower for one just gives a competitive advantage to the others. So, both the country's policy and the whistleblower shifting people or investments to other scheming countries or companies are each causing damage.
