It’s meant to be scary. I really think a lot of ndas are abused exactly because they are scary. The problem is they are expensive and uncertain.

Their validity is by state and enforcement is through the courts. Is a specific nda enforceable in your state? Is the other party likely to enforce it legally? Can you afford to defend yourself?

Don’t get me wrong,there are also many legit and enforceable ndas, which makes things complicated
