I always use Adblock. I also use Do Not Track, dot.js (to modify pages), Tampermonkey, Ghostery when needed and other extensions / scripts. I also clear my cookies upon closing the browser.
I don't care that I'm an "asshole". When I show less technical people how to block advertisements, the first thing they usually say is, "thank you!" or "can I buy you a beer?". I never met one person (other than people in marketing) that have said, "No, I'd prefer to see advertisements over content".
