I have my own unbound running on a VPS. My network intercepts all port 53 traffic, filters out ad servers, and then forwards over wireguard to my VPS. I should probably enable DoH as well. I'm feeling kind of lazy about it though.

I think ceasing to use your ISP provider's unencrypted DNS services will already bring quite some boost in privacy for the average internet user. That's why I recently switched to using DNSCrypt (https://github.com/DNSCrypt/dnscrypt-proxy) with one of the public providers listed here: https://dnscrypt.info/public-servers (pick one run by some university or internet activism organization).

It also brings an increase in recaptcha puzzles lol
