And as an advertiser, I confirm losing a lot of money trying to advertise, not seeing revenue. Choosing to advertise 25-34 males (in addition to being the definition of sexism/ageism) who type “Jira time tracking” (because “Jira” keyword is reserved anyway) is useless. I want to put an ad on websites that talk about Jira. And that requires no tracking at all.

It's only a big issue if you try to advertise a specific item on a generic platform; but if you can target websites that cater to your specific business, you really don't need anything more. Of course it means ad networks lose out since they can't just target specific people, they have to only target specific websites or apps.

Personally in the old days of newspaper ad's, I always wondered what the point was of anything smaller than a whole page; what is the point of a 1x1 inch ad in the midst of 200 others. Even today I ignore 99% of what's on the page other than the content.

Point of those ads generally is that people were looking intentionally at them for a plumber, sparkie, piano tuner, gramophone polisher, used tap shoes or what ever else newspapers used to advertise.

In fact many people only bought the paper on ad day.

Whole different kettle of fish.
