If I see a giant ad billboard, I can not look at it, look away, close my eyes, block it with my hands, etc. In a distant future I'd buy glasses that blur ads from my sight (if that could be done without a company seeing everything I see).
For me ad-blockers are the same with some automation. It's a way for me to not give up my time and attention for something I never asked for in the first place.
Moves like this one from YouTube are one step closer to that dystopian nightmare depicted in Black Mirror where you have to watch the ad no matter what. You close your eyes, and the ad pauses and only goes away after you finish watching it. It's absolutely insane.
We somehow got gaslighted into believing there's something good with advertising and there are just a few "bad actors" (where did I hear that before?). I firmly disagree. The entire world would be a better place without ads.
