@ryne It's not just about the ads: ad distribution networks are by far the leading cause of malware infections of user's computers! Ransomware dudes pretend to be advertisers and buy ad impressions then drop malevolent turdlets on the PCs of hapless victims to encrypt all their files and demand money for an unlock.
Adblockers aren't just for people who don't like advertising, they're absolutely basic internet self-defense against viruses and criminals.
