These users want to use encrypted DNS, instead of running unbound in recursive mode. There is a difference of opinion regarding whether encrypted DNS increases privacy - I contend that it does not and encrypting your DNS traffic to an upstream resolver who gathers all your DNS history requires you to trust that upstream service. In return, you gain no privacy since your ISP can see the plain-text request for any IP acquired through an encrpted DNS tunnel.
In my opinion, yes. Encrypted DNS provides less privacy, in my opinion. In addition, you get unfiltered replies - you are getting the IP address from the authoritative phone book of the internet, with no intermediaries to filter anything. You are in complete control and only have to trust yourself.
