Reap as you saw
That's what happens with rampant ad blocking. Ads will not be marked as ads anymore, because then they will get blocked, and there will be nothing left to pay for the production and serving costs of content. So, creators and advertisers naturally turn to formats where the ad itself is the content, which then in turn can't be blocked.
Don't expect anything to change till you keep systematically blocking ads that are clearly marked as ads!
