Youtube is now embedding ads midstream - I think it's just a matter of time before other providers adopt similar approaches. When adblockers were tools exclusive to nerds it didn't make sense to build countermeasures - as advertising has grown more pervasive and obnoxious adblockers have gone mainstream and there is now an arms race that adblockers are currently on the losing side of.
With adblockers disabled, I was seeing ads midstream ages ago. Ads that I don't see with an adblocker. Anecdotally, my subjective experience when adblockers are disabled seems to get exponentially worse whereas my adblocker experience seems to degrade at a much slower rate (e.g. manually skipping author recited ads on a podcast). Currently the TV is the weakest link, and people should be publishing layman's guides to pihole, or as others elsewhere have mentioned, refer them to a adblocking DNS redirect from an adblocker company. Midstream ads are especially obnoxious with music streams and I hope the majority's intolerance tips them over the edge.
Em... Adblockers still work perfectly? It's an annoyance to keep uBlock Origin updated, but it still blocks all ads on youtube. So it seems they're keeping up just fine.
