No entity has the innate right to psychologically manipulate me into contributing to its bottom line.
Your decision for what you buy or your decision to block ads? Which is completely beside the point of my comment. My point is that you are going to be manipulated whether you like it or not. That cute Bernie Sanders slogan, that "Eat the rich" slogan, all the beautiful art produced by your favorite political cause, it's all psychological manipulation by your definition (and it is). And by that point, all human interaction is manipulation.
Most of the stuff I buy is either commodity (clothes, always the same t-shirts, pants, shoes, my colleagues joke it's my 'uniform'), food, or weird-ass stuff that nobody advertises for. Like second hand computers or electronic components to build cool stuff.
And reviews I usually get in depth from other users on tech forums like XDA and local ones. Before I buy a phone I know pretty much every little thing there is to know about it :) Not just the gloss, all the annoying bugs too.
The only thing I buy that's really advertising sensitive is games I think. Or some hacker/maker stuff you'd see on hackaday. I know advertising affects me. But I'm pretty certain not a lot of my purchasing is driven by advertising.
> The idea of buying something based on an advertisement and not a need is foreign to me.
My point is that despite believing they have not bought something based on an advertisement, they have in all likelihood.
I'd take it for granted that zwkrt is not talking about reviews and glowing endorsements and sponsored videos or placement on store shelves or .. you get the idea. They're talking about ads! The crap that surrounds the real so-called content when you try to read an article without an adblocker. The nonsense that interrupts a movie on TV (or any video on YouTube) every three minutes. The trash results that gets a special place in front of all the other trash when you search on Google. All unsolicited, not sought for. I'd say if uBlock Origin doesn't block it, then it likely isn't an ad in the sense zwkrt means?
Buying something after seeking out reviews and seeing one that was biased and paid for could happen but it's not necessarily happening to everyone, and it's probably not what the fellow upstream meant when they said they find buying things based on an advertisement foreign.
This is where ads come in: a backpack company can run ads that should be shown to people interested in buying backpacks, and it’s potentially a win-win: you find a cool item that you buy, and the company gets a new customer.
And that best choice is probably from the manufacturer that spends the most on making their product. Not the one spending the most on advertising. This undermines the win-win concept.
E.g When you need something of you have 100's of options. If you saw an ad previously it now might be 1 of several products you compare as you are aware and familiar. The product still has to impress you on price and quality etc but the ad drove you to consider it. That is hugely important in a crowded marketplace. Also that ad might have shifted you perception of quality or features.
And ultimately 'need' is a very subjective thing. I highly doubt if you look around your house there is nothing you couldn't throw away and not get on with life as normal. Ads can make you feel like you need something at the time. That's why so many ads rely on fear based propositions, this emotion is strong in creating need like showing negative events for insurance.
