indeed, there are pi-hole block lists for ads, of course, but also malware, spying (including microsoft) and so on. Plus it helps with mobile ads in apps that you can't otherwise block.

I've never had a problem with ublock origin blocking anything I wasn't telling it to explicitly block, and, on android you can add ublock origin to mobile firefox which is a game changer.

ads are not just an annoyance they are a security risk and a vector for malware and spying. TV commercials are horrible as well
