I also have some very close to low fortune number / FAANNG tech CEO experience and was thinking the same thing. He was stupid to engage at all IMO - you did the right thing, Jensen did not. But, it's implausible that he isn't smart enough keep his lip zipped, if nothing else was.
China targets everyone of consequence, of course they targeted Jensen.
This may be a 'game of thrones' nefarious move by hostile foreign or domestic parties who want to wrest defacto control, perhaps angle to put their puppet in control, or otherwise leverage Nvidia by taking down its Founder and CEO.
It is completely unproven and should not be assumed that Jensen nor Nvidia took part in anything untoward at all. Historically, Jensen doesn't do stupid. So whether you like him or not, I do not believe he would be that stupid.
