I bought a piano course from Udemy because of advertising on FB (and then spent an additional £150 on a keyboard). I'm really enjoying it. Please tell me what a horrible human being I am.
In fact, in my post I explicitly assumed that nobody was made responsible for the task, exactly because I assume the poster is not incompetent.
The idea we couldn't find good products without advertising seems pretty moot with internet search available. The greater problem is seeing through the advertising to assess the product - there's a lot of things like market segmentation based only on different packaging (more wasteful, 'oppulent'). The Capitalist notion of value optimisation might work with false representation and coercion removed from the equation.
For me, that example actually serves as an extra argument against ads.
