Huang has been a great boss and steward of Nvidia, but ultimately falling for subordinates is grave enough, adding alleged Chinese spies, and allegations you sold Tencent billions of hardware through shady Singaporean companies for which the alleged spy worked etc and the board had no other options.
At this point it would be surprising if what we know is likely a small part and the Nvidia board saw enough very quickly to ask for his head.
He was responsible for hanging consumers out to dry by destroying the consumer PC market in chase of more profit. He is gambling with the world economy. He appears on interviews being a dick about all of this.
So I'd say this is very much in character for him.
His successor, however, probably got in position deliberately seeking geopolitical power. They're going to be worse in every way (except cheating on their spouse with subordinates, they're probably not going to do that).
After all, when you see two ants in the kitchen..
