We don't do third party ads. We block third party tracking which takes out third party and most first party ads. We also block fingerprinting, cryptomining, and other threats.
Are the ads hosted by the websites your users visit? If not, they're third-party ads, with you being that third party.

Oh don't worry, I'd make the exact same comment from my other (non-green, thousands of karma) profile, I just like to occasionally switch aliases.
If you insist on a reductionistic definition that rules out anything other than a static ad on the same site as the publisher, you will get stuck trying to improve the Web and how it is funded. I understand objecting to all ads other than static images that click through into same origin forms, or whatever, but that won’t pay the bills for most publishers.
