This article doesn't really say much, but it raises an interesting point. As a user I'm often annoyed by ads (especially big flashy banner ads that also happen to come with sound). Google's ads I don't mind so much except for sites that seem to have ads placed in 3 or 4 different places (across the top, a side bar, in the middle of an article and somewhere at the bottom). So I can see AdBlocking being useful (although I haven't used ad blocking tools for a while). From the point of view of a web startup however advertising is what pays for the content so the users don't have to. Users end up paying with their attention instead of dollars. So when they try to subvert your ads they are essentially violating your terms of service.
