I hate advertising because it’s nonconsensual, subconscious manipulation. When I see an ad for product X, I’m more likely to buy it in the store than product Y because there’s artificially increased familiarity for it in my brain. If the purpose of advertising was to inform, you’d never see an ad for Coca Cola, since everybody on the planet knows about it already. The %0.01 of advertising that informs me of a product that I might actually purchase can die overnight, and I’d not notice a difference, because I use adblockers and when I need something, I
search for it on the internet, Google, Amazon, and the like. When I need reviews I turn to Reddit and HN.
If advertising is a zero-sum game between companies competing for your eyeball-minutes, allocating double digits of their income to marketing departments, it’s a net drain on the economy. If it’s a positive-sum game for companies and you are purchasing more goods than you otherwise would because of the ads you see, it means you are purchasing stuff you don’t need, and it means advertising is a way to funnel your money to companies through nonconsensual means, i.e theft. In reality it’s a slightly positive sum game for companies.
Advertising is cancerous in the sense that if there was no advertising, nobody needs to advertise, but if somebody is advertising and you are not, then you’ll lose market share and die, so you advertise too and hence it spreads. It is parasitic in the sense that vast amounts of collective resources of society is spent on this redirecting-money-from-company-A-to-company-B scheme with no positive value generated.
Political advertising undermines democracy. Ads have a huge influence on the outcome of modern elections. You need billionaires backing you to fund your campaign, and guess what? Those billionaires will have some special requests when you take the seat. Fair elections and leaders caring for the people are only possible in a world without political advertising.
All arguments in favor of advertising are circular, they presume the current economy/society where everything is heavily dependent on advertising and then point out “Look, but X wouldn’t work without advertising!” In reality a world without advertising would look much different, and my hunch is it would be wealthier and with less inequality, too.
