everyone who accepts a payout from meta agrees to be bound by the non-disclosure agrement from the employment contract.

They also agree to a non-disparagement agreement. this is where Meta agrees not to chat shit about you, in return for you never talking publicly about them. The problem is, thats a fairly effective tool to enforce a lowly employee not chatting shit about a former company.

What I don't know is, what her penalty is. Espcially as both parties have disparaged each other publicly.
