Sure, that could be influencing my reasoning, but it goes the other way too. It's easy to criticize ads as a business model when you don't have skin in the game (ducks). That's why I decided not to bring up either of those points: I'd rather write for people who are willing to focus on the argument instead of assuming bad faith.
But I have it easier in this case - because I view subliminal manipulation in advertisements as something horrible. Freud's legacy is one of deception for profit, something immoral right at the core. Creating useless needs, producing useless goods, deception has become the norm. The playing on the weakness of the human mind is something horrible. It makes a mockery of our intellect.
