People will block ads when those ads become a nuisance to them while browsing.
the problem with these ad blocking things is that they tar the whole web with the same brush. some popular site might start showing pop-ups, so people install an ad-blocker, but then every other site they visit loses out too -- even though their ads might be perfectly okay.
its like people putting a sign on their door saying 'no junk mail please', but getting all the innocent billboards, tv ads, newspaper ads and radio jingles wiped at the same time.
