Earlier quoted context omitted.
I don’t use an Adblocker due to ethical concerns. (Not trying to convince you to do the same, just explaining.) It’s, uh, really not that bad. I rarely notice banner ads and the like. If a particular site gets really egrigious, I leave the site. I suspect that after using Adblock for years, your brain has forgotten how to ignore them.
My brain shouldn't have to ignore them, though; that's what technology's for :)
As for the "But how do we pay for all these free things then?" counterargument, I'd suggest voluntary restraint on the part of website creators. I can live with a few modest JPEG-only banner ads hosted directly from the site I'm visiting. If a site promises to not use animated images, streaming video, streaming audio, any sort of trackers, any sort of third-party content, and if they keep the screen-real-estate ratio of ads to content relatively low, then I'll whitelist them in a heartbeat.
