I wish more people understood this. We're in the middle of an unsubstantiated moral panic, like the old "video games will make kids into killers" panic that turned out to be totally false.
MySpace used to have animated DoubleClick style untargeted ads. It sucked. Facebook crushed them partly because it's a much cleaner experience and Facebook ads are so much higher quality.
The problem with all the people claiming this sort of move is great is it doesn't ring true, they sound almost in physical pain over "tracking" (a scary word for very primitive and broad-brush techniques, by and large).
But where are the people who have actually suffered concrete, quantifiable harm? Some real, unarguable case where someone suffered because of ad targeting? If there were a real harm here, given the enormous scale of the internet, there should be millions of such stories but the only one I can think of was years ago, about a supermarket that discovered that women who buy X, Y and Z things together are very likely to be pregnant. They caused a minor family drama by sending a teenager adverts for baby stuff when her parents didn't know. Arguably this is a hole the teenager dug for themselves, but even so, it wasn't even internet based stuff from what I recall.
And as far as harm goes, that's about it. I've never been harmed by ads. I've never met anyone else who has been either.
But I remember a LOT of people complaining back in the bad old days about the barrel-scraping punch the monkey inventory that typified the web experience.
