I don't understand what is it with DNS-based blocking people that they seem to be some of the most annoying proselytizers. Anyone remembers the "HOSTS file guy" from Slashdot ?

DNS-based blocking is as much a "future-proof" technology as "just don't look at the adverts". DNS-based blocking is old, easily workaroundable by anyone (just use the same domain name for everything, or interchangeable domain names, or just don't rely on system DNS), and significantly less featureful than even the simplest DOM/JS-based blocking (e.g. good luck collapsing ad elements from the view, getting Youtube not to play ads, etc.).
