as in all trades in the world...for example, pseudo vaccine merchants.There are also a lot of charlatans who are not there only to make money.
Except that the term charlatan is misused since everyone believes they are entitled to decree that such and such is a charlatan. Except that some do not distinguish between true and false quackery.
For example, for pseudo-zeteticians, everything that is not in conformity with conventional medicine is charlatanism and swindling, like ABCile and Izmentrop...and others!
However, charlatanism, already seen, corresponds to precise criteria[*] and not left to the interpretation of each one.
[*] as the term pedophile which does not include eros.
