There was a Firefox extension long ago that did NOT block ads but hid them. Basically it loaded them and for all the site knew, the add was showing, so it was transparent.

But, the ad wasn't rendering in the page. So the user didnt need to suffer them, but the website owners still profited.

The only losers where ad buyers, who IMHO are exactly the ones that should be affected.until they realize that ads are not effective.

Someone should bring something like that for current platforms. Even for video like, a placeholder video with a tip, interesting fact or whatever, playing while the page load the real video.
