No, I can't provide a cite. Insider information. But whistleblowers have been threatened with being "Shwartzed" since (e.g. have frivolous criminal charges filed, to make their lives hell). In every case I've seen, whistleblowers signed an NDA, a non-disparage, and backed down.

That's why I don't trust a !@#$% thing from MIT anymore. Lies and fraud get covered up. Once that starts happening, you can't trust anything.
