NDAs are hard; there are good reasons for them, but they are too-easily proffered and too-often signed.
Where possible, they are far more humane if they have a reasonable end-date.
At the end of the day, these agreements (and non-competes/non-poaching clauses), among well-intentioned people, can boil down to the spirit of Stuart Freedman's request [1] that Gerry Garvey memorialize an oath: "I swear that I will not screw you unnecessarily."
These agreements, however, are a bulwark against the ill-intentioned and malevolent.
