Even with a NDA, you can still go to the authorities to report illegal acts. You just can't monetize your past employment in the form of a 500k book deal. Between the public's interest of crimes being prosecuted and the freedom of individuals being able to enter into agreements, I think that's already a pretty fair trade-off.

> you can still go to the authorities to report illegal acts

that authority could be birded by corp and report will go nowhere.

> You just can't monetize your past employment in the form of a 500k book deal.

sure, its reasonable to have non-monetization clause in contract, but it is unreasonable to have blanket statements to not ever talk about events during employments under any circumstances, which likely included into NDA.
