why don't we block ads at the operating system level instead at the browser level? If we are talking about having more security and performance wouldn't it more sense? Not sure I understand how ublock origin works anyone have a summary on this?
Also it would be impossible to perform cosmetics injections (scriptlets, alterations of the DOM, etc.)
It might already provide a good base-line but definitely not enough for all cases (e.g. YouTube ads, etc.)
the value of dns/ip level blocking is diminishing as resource density per host increases due to ipv4 shortage and should be completely inpractical with ipv6 due to adress space size.
sure, we do that, too: https://github.com/StevenBlack/hosts
