Elon Musk seems to care a great deal about a lot of stuff that frankly isn't any of his concern, not really. Trump care immensely about shallow stuff that's really below what the president of the United States of America should spend time on.
Altman has some reason to worry, because developers and the users of HN are then ones he needs to promote/hype his products. OpenAI still needs customers and they need to sell tokens and a large number of users on HN are not only not buying, but are becoming increasingly hostile towards the product Altman is selling. My guess would be that he'd assume that the users on HN are in some sense his peers, and they are currently extremely divided in the question about the value and dangers of LLMs, and are increasingly critical of the business practises of OpenAI (and other AI companies).
