But as most of the companies providing and running ads are very much on the tracking users business, e.g Google/Meta/Amazon/Microsoft etc, I'd imagine they won't be very willing to provide your site with tracking free ads, and the smaller companies that would, probably can't provide anywhere as nice of a payout.

So you are left with the people who would be willing to reduce their profits for the benefit of their users, and looking at what a shitshow todays internet is, there's maybe a dozen of those left.
