Yes, Fauci's flaw is he is too truthful, even when the truth doesn't meet the president's #1 goal which is self-preservation.
I think I would do the same in his shoes if I thought it would save lives. Doctors have sworn an oath that should take precedent over loyalty to a politician.
You are right he is in charge and can try to make people loyal over anything else. I just think it's morally wrong and it's going to get a lot of people killed.
Good luck with that.
