I know what you are trying to say, but for many people outside the US, Facebook is a foreign tech company. What makes US nationals any better in safeguarding sensitive data/access about the companies customers than people from UK or Canada or Germany or Norway or Australia or New Zealand etc?

Should a tech company silo its data and operations so each country has its own independent unit? No, too infeasible and defeats the purpose for a lot of their services.

The problem isn't just foreign nationals. There's plenty of CIA inside FAAMG.

It is always a mistake to use nationality as a proxy for trustworthiness.

Being a US person, personally I'm much more concerned with the negative impacts of US spies spying in the US than foreign spies spying in the US.

Foreign governments don't regularly go around mass murdering and torturing Americans the way the US government does.

Americans have a lot more to lose from CIA spying than they do from Saudi intelligence agency spying.

Please elaborate on what the insanity is.

You're kinda right, but on the other hand how I'll get visa and steal some faamg jobs if they'll not accept foreigners? /s

ok, just kidding, now serious take:

US population: 330kk

Rest of the World: 8kkk

Delta (8kkk-330kk)

Even if we assume that distribution of highly skilled people is not uniform (lack of decent higher edu places, harder access to computers/internet)

then you still lose shitton of outliers

edit.

ops I misread.
