The goal isn't to "harm the employer", the goal is to expose their behavior. If exposing your "internal operations" harms you, the problem isn't person doing the exposing, the problem are the "internal operations".

I find it fascinating how everytime someone makes scandalous practices public, people come on the scene to condemn the people who go to the public.

If there is no legal way to publicise abhorrent practices, we must break the law. Especially if "breaking the law" is something as harmless as lying on a resume.
