This is a false (and dare I say dishonest?) analogy. Reporting crimes is protected by law [0]

If the author would report a crime she would be protected. The author is just airing some dirty laundry. She was paid money in exchange for not airing said dirty laundry. Hence her troubles now. Cry me a river.

I don’t take a position on this because I don’t know it but I think you’re (willfully?) misunderstanding the point. I don’t think all ethical problems can be legally defined. Something may be legal and wrong or illegal and not wrong. If she was indeed forced out for reporting sexual harassment, then what ethical responsibility does she still bear towards that company, regardless of what they ask her to sign as she leaves? The point isn’t that she’s right or wrong for sure, it’s that the problem is complex and legalities cannot account for all situations.
