Sam Altman is one of the most well connected people in Silicon Valley.
And investors like Reid Hoffman aren't having their lives being dictated by Musk.
However, Mr. Musk is continually called out by OpenAI in the public and OpenAI has quite the megaphone.
From what I see, this is mainly due to Musk complaining loudly in public.
And unlike the caving instructor that Musk libelled, OpenAI has the means to fight back as an equal.
That said, I don't see anything in this post that I'd describe as Musk "being called out".
