> Do they just get paid out with restrictive NDAs?

Yes, that's a very common part of an exit package for executives. Speaking from some first- and second-hand experience, you can get paid a hefty sum (6-12mo of salary worth of cash) for signing an agreement that has some amount of limits on what you can say, to whom.

There's also some kind of what I think of as a LinkedIn effect - there's a disincentive to talk trash about any organization publicly, since that's now attached to your name and might make future employers/organizations leery of hiring someone who might air their dirty laundry.
