But this isn't about exposure or impressions. This is outright stealing. There's a certain portion of users who will never click an ad and blocking them out completely is really no loss. But what's happening here is that ads are still displayed and in the event a person clicks the ad the revenue goes to someone else. The visitor didn't come for the ads, they came for the content. So the plugin maker is basically a leech. Replacing another site's ads with your own and taking the revenue is theft and if it happened to you I'm not sure you'd feel the same way. You know damn well your suggestion is totally unrealistic but it totally misses the point anyway.
