There are acceptable ads, but the Acceptable Ads standard is not acceptable. If you read the standard it only addresses UX concerns, which are intended to address ridiculously annoying pop-ups, etc., but have nothing to do with ad privacy.
There is only one way to advertise in a privacy-respecting manner on the internet, and it’s by serving ads from your server depending on the content on the webpage, instead of hosting third-party ads which depend on the visitor.
Static sponsors, like someone who sponsors the Techlore forum getting their logo shown, are fine. Context-aware ads, like an advertisement being shown based on your search query on DuckDuckGo, are fine (as long as there is separation between the advertiser and the visitor so that the advertisers never have knowledge of who viewed their ad unless it’s clicked).
The moment you embed Google’s iFrame or another third-party tool, you’re no longer privacy-respecting.
There is certainly another argument to be made that all advertising is bad, and/or that all advertising should be blockable by users, and I think both of those arguments are legitimate, but neither of those arguments relate to privacy specifically, so it ventures into off-topic territory.
It’s a bit strange, but I don’t know of any ad networks like Google AdSense which run server-side. AdSense only does server-side ads in Google’s own search results, but website owners can’t use that tech. I bet there is one out there though.
