In a weird way it manages to fix many people's problems with advertising. Ads are sometimes horribly intrusive (to the point that ad-blockers are necessary to me) and it forces companies to adhere to some kind standards when none are technically required.

On the other hand; it's blackmail. It also falls apart if there are too many competing services or people generally catch on and switch to another ad-blocker. Then companies either pay N-vetting services or their investment is completely wasted. The end result is an (arguably) overly-strict vetting service because people will switch if they don't block enough ads.

As a consumer; I just wanted an ad-blocker sooo....
