That's more internet chatter, as far as I can tell. I've never heard him speak with arrogance. He often says, "I'm doing my job," when confronted. He bases his advice on medical science. He has been heavily criticized by the right for changing his advice, but as he also advises, the virus is changing and scientist are still learning new things all the time. He's gone out of his way not to politicize his work (he's served under Reagan, Bush I, Clinton, Bush II, Obama, Trump and now Biden). I think it is also fair to say he has well more than average experience with infectious diseases.
I'd like to see the comments from "other scientists," and get a good look at their credentials. Keep in mind, there are "scientists" who claim global warming/climate change is a hoax. They are few, and mostly work for the oil and coal industries.
