You mean, no other evilcorp will hire them afterwards?

Not me. But these are all "most important people in the world." So should fit their own narrative.

Just, Devil's Advocate, but what would be the benefit of your career if all humans (or even just a few billions of humans) are going to die?

I think it's reasonable to assume that if it's not worth breaking the NDA, it's likely not an existential threat for the vast majority of humanity.

Now, does that mean that people who currently work upper-middle class knowledge work jobs aren't in for an exceedingly harsh economic reality check? Absolutely not.

But that's not really as serious as an existential threat to humanity.
