I agree that you have a point because I can be open-minded but in the real world, multiple things can be true at once. This is not either black or white thing like you are making it. Shades of grey can and do exists. But you simply might not know that, perhaps out of ignorance.
For example, albeit related, Fauci is entitled to money on some HIV treatments by owning methods of delivery of said drugs. So he does not make money via the drugs themselves, but the administration of them onto patients. So it is not like he is not new to the concept.
