Ars Technica takes a pragmatic but tough stance on ad blockers, turning off the website's content entirely for users who refuse to look at arstechnica.com ads. The freedom-fighers in the comments (and, I imagine, pro-ad-blocker folks like David Pogue) are mad, but Ars makes a good point from which they refuse to back down. "[If you won't whitelist our ads] please go get your news from a higher quality source. As it stands you're a net loss to us." Great read.
