>Search advertising is sold on a CPC basis because it is intent based. Display advertising is by and large sold on a CPM basis. You don't get the impression and the publisher doesn't get paid. Some will label this "theft". Actually Google is the thief here. Advertising and JS/Client Side analytics/scripts suck up my CPU time and use up my bandwidth that I pay for. All the ad-block user does is block bits from showing up on his/her own personal machine. Blocking external data from unknown/untrusted sources is theft now? Also, since we already know that compromised ad servers contribute to the proliferation of malware, its also a good security practice. (Okay maybe not static image ads, but definitely flash ads) >Frankly I'm more inclined to trust the Googles of the world than I am some guy who writes an extension. That is true in the general case, but there are several opensource extensions. And people can find out what exactly happens with their data unlike Google.
