I daresay even the "debunkers" are profiting off the misinformation. It doesn't need to be debunked anymore. I think the demand for this material is created by mid-low intelligence level people who want to feel smarter than (those who they perceive to be) "believers", of whom nearly all are, for various reasons, trolls.

Just by repeating the words "flat earth" the debunkers are giving it a platform, and thereby profiting off it.
