Last time that I brought a (local) technology magazine it was filled with ads. Paying for content and ads are not exclusive.
Imagine, when buying your groceries, you had to pay half cash, half by prostituting yourself. Nobody would want that.
Though, prostitution is a valid funding model, as sex workers earn a living with it.
To extend the metaphor, I see advertising as some kind of prostitution for my brain. I do not want that for my brain.
