The US Government is using NVIDIA chips for all sort of stuff across all classification levels. Subsequently, Jensen has deep relationships within the government that warrants additional scrutiny.
Him authorizing his company to sell massive amounts of chips to a restricted country is massively illegal, but companies work around that and have since forever. Doesn't make it less illegal, but that's only a small part of the problem.
The real problem is that nobody knows how much sensitive info Jensen gave this woman or how far that info spread.
It's really about fairness. Us technical salespeople take training that tells us all of the ways that deals with restricted countries happen and how we will immediately get fired ten ways to Sunday if we forego that to close quota. Also, normies with clearances tell their partners stuff they shouldn't. Stuff they think isn't really sensitive since it seems so minute. This isn't bad until said partner spills at the wrong place and wrong time. That's how normies get sent to prison for treason. Loose lips sink ships and all that. [^0]
Getting fired -- WHICH HE ABSOLUTELY SHOULD BE -- is the least of his problems.
