We have centuries of evidence that unpersonalized ads are both the best for brands (if you aren't preaching to the choir you are opening the door widest for expanding your buying audience) and individuals (discovering things that you didn't know you needed, discovering things that other people in your life might need but aren't directly relevant to you, avoiding the mental health detriments of how the more targeted an ad becomes the more likely it uses psychological tricks to manipulate you [all advertising is manipulation; but the amount of manipulation you can get away with in a general ad is very different that what we are seeing in targeted ads], etc).

The only people really benefitting from targeted ads are the companies making the ad tech (including and especially Google) making billions of dollars from "platforms" that do way too much to prop up "metrics" that mean way too little in practice (but are great for creating fancy invoices to charge just about whatever you want to the rubes [sorry, advertisers]).

(I've been taking a lot of steps to opt out of personalized ads, without outright running ad blockers, though these days a lot of sites now believe Firefox to be an ad blocker, and the ads are better unpersonalized. It's just amazing that so much of our culture on either side of the ad tech "platforms" has been sold such a bill of goods to think that personalized ads are doing anything but sucking money out of good companies into at the very least morally gray if not unethical ones.)
