Pi-hole has been a godsend. I use it at home and at work. Fuck ads. Seriously, there is a history of a lack of security and "give-a-shit-itis" about privacy in the whole of the ad industry. If you have $70, get a raspberry pi, load it up, install pi-hole and fuck 'em at the network level. We do this on our public patient-facing wifi as well.
The lack of security is actually crazy. Go to a random website, look up what U-Block origin is blocking, and Google some of the add networks that show up. It's crazy how many of them are on sites that help people tackle malware issues. Shoot. That virus that got my Android phone? Five bucks says it got on there from some kind of ad network exploit because ironically, the only third party app I ever installed on it was MalWare Bytes.
