It sounds like she did step 1 (try to change from the inside, first privately, then through employee protest), and now she's doing step 2 in your program. What would you do differently?
Most people would keep taking the check while convincing themselves they're not responsible.
When the somewhat immoral nature of that intrudes on people's thoughts, they can sort of silence it by finding fault with the person who IS following their conscience.
So if the company were you are working at, treats you badly, you would resign over going on strike to force a change and then stay at the company, for example?
I would (and have). Trying to change the company hurts you and helps the company (that was treating you bad). Just leave. Save your energy, don't put any information public that will make you look like a bad employee and find a better job. The best revenge is living well.
