Just so I don't get accused of shilling out of self-interest, I don't work (and never have) in advertisements in any way shape or form, nor does my employer make a dime from advertising. This advertising discussion always ends up with two sides: "so what?" and "advertising in any form is evil and everyone involved in it deserves the death penalty" (hyperbole but not by as much as you'd think).

What the former side ignores very often is that there are scam ads to scam websites that are basically malware. The ads with fake sign up buttons, the flashing ads saying you've won money, basically any video ad I've ever seen. They're garbage.

What the latter side ignores is... basic human agency? Nobody has ever had a gun to their head and been forced to buy a salad spinner off of Amazon because they saw a banner ad or read a sponsored article on a recipe blog. I have regretted purchases I've made, and some of those were probably only made because of an advertisement. That's my fault, not the advertiser's. If you don't want to buy something in an ad, don't buy it. A company having more fine-grained detail about your socioeconomic status or third-party purchases does not remove any of your agency.
