Ethics of con artists

[brewer]

There are much worse cons for money. Examples: Theranos, Purdue, Mylan, Juul.

Should we throw organized religion and chiropractic in just for kicks?

Absolutely consider those and all others.  I just seeded the conversation with the covid treatments but that's not even scratching the surface.

I wouldn't consider Juul to be a con, though.  It delivers exactly what it purports to deliver.  Is there some misrepresentation in the product?

Chiropractic for sure, at least some aspects of it.  There are some legitimate aspects to the practice and a large number of its practitioners have stopped making all of the woo woo claims, but some are still at it.  So overall I still consider it a pseudo-science.  At best its a very expensive massage.

Yes. Do a quick google 'juul product misrepresentation' and read.
