Even the large ad networks show paid content that violates what I would consider widespread ethical norms - presenting everything from hyperbolic claims to straight fraud to people with little repercussion. I'm reminded of a poignant example in television, where episodes of Jeopardy! are intertwined with their shilling quackery like Prevagen to an audience using the fear of aging. Perhaps I'm growing increasingly blind to any positive impacts of the discipline, but ethically I find it hard to separate the fraudsters from the engineers that enable them.
I guess advertising is saving me a lot of money in the end by cultivating this hatred, and though I can't change the world this screed was therapeutic.
