As the article states, Singapore accounted for 20% (!) of Nvidias total revenue. You think management wasn't aware that something was going on? A country with about 2% of the GDP of the US and non of the large AI companies? Management either was involved or willfully looked the other way the alternative is that they are so grossly incompetent and non-involved in the company that it's hard to believe.
That’s like getting surprised that Delaware accounts for 60% of Fortune 500 companies. Singapore nowadays is the main financial hub that connects the East and the West.
