There are no allegations against Nvidia there.
It's absurd to suggest that Nvidia would need to secretly ship a handful of chips to some sketchy actor when Nvidia chips have a a mile a line long for sales.
Jensen can sell his inventory 10x over. You have to have buying power just to get a hold of them.
Anything is possible but it would be extra stupid for one of the smartest people in the world to risk everything for literally no reason at all.
