Also, I want to emphasize that shady shit in the marketing industry is so widespread that "the shadier side" doesn't refer to just a few companies; it refers to the shadier side that almost *every single* company in the marketing space has, ethical companies are vanishingly rare and the whole industry is Like This
A separate but related point: the shittier companies are allowed to be, the more susceptible people will be to scams.
Because how do you expect people to distinguish between the scams that are state-sanctioned, and the ones that are not?
