the point for me is the visual noise, not the memory that ads consume. Actually, normal users are used to the lag, they don't see it as much as we do. You can take a look at consoles that have run games at 30fps for decades and nobody complained.
People install adblockers because too many idiots became too fucking greedy and ruined ads for everyone else!

Yes! And the cognitive noise. I find it literally impossible to read text if there's some blinking ad nearby. Before Adblock I'd have to put my had up to the screen to block the animation so that I could read the article text in peace.
