How to deal with censorship

Ow ps, you mentioned Unbound.
If this was installed using a distro with a recent openresolv package:

pi@ph5b:~ $ apt policy openresolv
openresolv:
  Installed: 3.12.0-1
  Candidate: 3.12.0-1
  Version table:
 *** 3.12.0-1 500
        500 http://raspbian.raspberrypi.org/raspbian bullseye/main armhf Packages
        100 /var/lib/dpkg/status

And below file exists (it doesnt on my setup):

pi@ph5b:~ $ sudo find /etc/unbound/ -iname resolvconf_resolvers.conf
pi@ph5b:~ $

I advice you to do below to prevent unexpected/improper behaviour (DNS loops etc):
