Haha, yeah what idiots.
Obviously we all know what dns we should be using for privacy but maybe someone should say it out loud in case someone doesn’t?
If you've got some free time and a spare computer, pihole with recursive DNS, it blocks ads and queries the root DNS servers itself (requires some extra set up though).
Other services like Quad9 are good for networks other than your home though.
I currently use NextDNS, it’s cheap and works great. You can basically set it up like a pihole, so I have ad/tracker blocking across all my devices and anything on LAN.
Personally I use the cloudflare option but specifically route the DNS traffic, along with everything else that can be out a pair of tunnels rather than the WAN to merge it with everyone else using the same endpoints, but whatever solution works for you.
