That's terrible that someone did that. I think that's wrong, and people that do that should be in prison.
But if the rest of what was written didn't matter, it wouldn't be written. He thought it was important enough to put it in. It's there to be read and discussed.
And I have to point out, we're not talking about a couple off the cuff remarks he may have rushed. About 95% of the post is about his ambitions for OpenAI. So pearl clutching that people are actually discussing the meat of the post in a tech forum reads performative.
