Advertising should be viewed through the same lens as code injection is in computer security (when an attacker gets a computer system to run a program that it actually shouldn’t and that usually benefits the attacker).
The point of an advertisement is literally to inject the idea of a need into your mind, a need that you didn’t already have before (“You do actually need a new car.”), or a more specific version of an existing need (“You’re need food? You should really eat this!”).
It’s an attack on the integrity of your very being and it should be defended against.
It’s also clear through the language that is used in making and distributing ads:
They are “aimed” at a “target audience”. They even have “penetration”.
These are words of warfare, and they aren’t there by accident.
