Since most ad blockers are whitelist-only, I assume that people using a blacklist ad blocker are explicitly blocking sites with annoying ads. Of course that's merely a generalization based on how I think I would use it. If the stats are shown historically, a site owner could see that after a redesign or some changes on their site, or maybe after signing up with a new ad vendor, that there was a spike in their ad blocks and rethink their design or deal with said vendor. I don't know if any of this would play out as I'm visualizing it, but I do feel opening up the conversation between site-owner and visitor to figure out what can be considered useful advertising is good for everyone.
