He literally has children with Shivon, who is an employee / direct reportee informally in at least some of his companies.

Has Shivon been implicated in billions of dollars' worth of export control violations?

(Also not batting for Elon, but you asked for reasons why people would care about this scandal more.)

That's a fair point. I wasn't aware that she had a reporting chain to Musk, but it seems that she did when she worked at Tesla and Neuralink.

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.
