I don't think it's money. As others have said there's not enough money in it. My guesses are the following. Survivorship and confirmation bias. If a thousand doctors try it out then a few of them will statistically see incredible results. They will then be "on board", confirm amongst each other, and be skeptical any data that shows otherwise. Plain bias. Just being anti-vax and jumping onto anything that avoids vaccination. Or being anti-government and jumping onto anything that is opposite of what CDC promotes. Or being among the anti-science variant of religious and jumping onto anything that shows religion over science. It's not particularly these people's "fault" that they're behaving how they do. It's just human nature. There are others that I think are doing it primarily for notoriety. Joe Rogan, Simone Gold, etc. But the thing is, the people enamored with the anti-science or anti-vax or anti-government schtick are going to find someone to champion their cause, and once you start down that path it's hard to turn back.
