Musk has 4 children with a neurolink exec that reported to him. She was also on OpenAIs board until 2023, where she fed him confidential info about the company . The relationship has been ongoing since 2016, but was kept secret until 2022.

He kept a lot of his relationships secret, including offering to pay right winger Ashely S. Clair over 10 million/yr to sign an NDA that would prevent her from ever stating she had his child, until he got a position of impunity that thar unlimited wealth and political favors buys you.
Let's not forget that if almost anyone else did what Musk pulled with Starlink in Ukraine he would get a 5 am visit from counterintelligence at his house the next day.
The difference is that Musk is an actual oligarch and Huang is "just" a billionaire.
