This brings an interesting twist to the question: "is blocking ads on a website denying the owner their revenue stream and therefore wrong in some way?"
How is this an interesting twist? As a website owner, it not just as bad -- it's worse, because it gives the user an additional incentive (beyond convenience) to block my ads, and feel self-righteous doing it.
Editorial ads :-)
Oh, absolutely! But that doesn't mean I want to see the Adsense/Casale revenue dry up at the hands of some opportunistic do-gooding scheme.
Well because I suspect a lot more people would consider this "
wrong - which lends strength to the argument that ad blockers are sometimes unfair
Just thinking out loud, but the website owner could add a clause to its terms of service that explicitely forbid this - it could become a motive for account suspension.
How would they notice? And aren't we mostly talking about sites that don't have accounts to begin with?
It'd be sad to see it come to that. Additionally big sites have a high proportion of readers who are not registered with accounts.
