Jensen had the choice of coming clean like this, where half of Silicon Valley is rallying to his defence and he remains a multi-billionaire (and maybe saves his marriage), or having this exposed by the new Congress, at which point all manner of punitive countermeasures against Nvidia are on the table.
Currently, Energy & Commerce and Oversight & Investigations are asleep. Come January, they won't be.
Huang, like a lot of Silicon Valley, thought their guy would stay in power and protect them.
there is possibility someone overplayed their cards and didn't think of possible consequences, OTOH maybe they wanted to kill two birds with one stone
Cf. the open secret nature around the entire Epstein cabal.
This framing is plain silly because it ignores the sequence of events. NVidia conducted an investigation after Huang admitted to having an affair with someone the US Government believed to be a Chinese spy, and in any case NVidia sold billions worth of embargoed chips to that company (and now it seems we have some proof per another HN front page story that the latest leading Chinese open source models were trained on embargoed NVidia chips). So then the other 2 instances of infidelity came out in the course of the investigation - of course as they definitely should, otherwise it would be a really shitty investigation! And sure, it was known by at least some number of other NVidia employees that Huang had relationships with subordinates (at least according to reporting). But that doesn't change the fact that Huang's relationship with Alice Huang was not known (and in fact denied by Jensen Huang) before this all went down.
It's not like Huang's 3 paramours got together before the investigation started in some sort of nefarious plot.
