I think you’re right and that is how the word is most often used, but at least merriam-webster gives a broader definition, as the “practices or pretensions of a quack”, which it then says is the same as a charlatan, so I guess it would be acceptable. I’m not a native speaker, however… :)
I hate the term “pseudo-science”. Call it what it is: quackery.
I was under the impression that quackery was specific to medicine.
