Have you considered that perhaps it's not the ad itself but that it just takes a 15-30 seconds of a delay to maybe realize that you're about to waste your time / ease your boredom that maybe keeps you from playing?
Every ad on YouTube makes me reconsider how badly I want to watch the video. Lots of times I just close YouTube and pull up Bitchute.
Tangent: Is there anything on bitchute that isn't right-wing or conspiracy theory? I've just pulled it up for the first time and by the front-page videos it's an alt-right cesspool. I'll use the alternative if it's viable, but this content isn't.
