I'm not seeing good and evil in this post. It's calling Sam out for not being transparent. Given he's elevated OpenAI, in public testimony, to an extinction-level threat to humanity, that lack of transparency is of public concern.
Not being transparent doesn't make him evil, doesn't mean he is unlikeable and doesn't per se mean he's dishonest. (Though OpenAI and he do have a likeability problem, at least in politics, albeit one I think they can fix.)
