"the three jumped ship to a UAE-based business"
And there is the problem : Uncle Sam let them out.
I think that, if you are working for a company that requires governmental approval to export what you are making, the government should also have a say in who you are allowed to go work for outside USA borders.
Yes, I know, it is a restriction of individual liberty, but honestly, it seems to be a necessity as well. These three not only brazenly quit to go work directly in the UAE for a competing company that openly worked in the same domain as the company they left, but they also recruited ex-colleagues, meaning yet more brain drain going where it definitely shouldn't.
And it would seem that they had no problem putting almost $1.7 million on the table to stay out of prison. I'm pretty sure that that means they have a lot more than that stashed away somewhere out of Uncle Sam's reach. They profited handsomely from torture and unjust surveillance, they should go to jail.
