I cant find any sources stating that Dushku's husband would be a billionaire. Rich, sure. Billionaire, not so much.
Whistleblower in the current USA means prison, and be happy if thats all you get. I would not advise anyone to be a whistleblower in the current USA, and if you want to be one, well be very very careful. Sure, Edward Snowden got away, but Juliane Assange had much less luck. Its funny how those who report on the crime receive the harshest treatment, those who did the crimes get no penatly, and yet the US public doesnt seem to care.
Fortunately Dushku's reporting about sexual harassment, which doesnt challenge power, so she's excempt from such treatment.
Still its weird she needs any special rights to violate her NDA. Any NDA that blocks people from reporting sexual harrassment should be illegal in the first place.
