I don't know anything about Adguard, but good on the team for doing the extra digging instead of just going along with the claim. Even better that they're sharing what they've found with everyone else.
I tried not to share too much details while we were still in process of figuring out the details.
The legal advice we got was basically “block asap or risk jail time”. Moreover, the risk would still be there even if the complainant is shady or hiding their identity.
So it took us some time to do the digging and make sure that illegal content was removed which was the prerequisite to unblocking.
The digging is not finished btw, we’ll later post a proper analysis of our reaction and the results of the research.
I would advise against using unbound on the client side as this way all your DNS queries will be unencrypted and visible to your ISP. Besides that, the DNS responses can be modified, this kind of censorship is very popular and used in many countries.
IMO it is safer to use a big popular DNS recursor (google, cloudflare, adguard, quad9, etc), use DoT/DoH/DoQ and maybe add some additional filtering on top of it.
You can also install AdGuard home as a home-assistant add-on, and then configure your router to hand that IP out as the network DNS server -- so all of your network traffic is ad blocking as soon as it hits your wifi. (like a pihole).
It's pretty slick, highly recommend.
(Also super useful to see what devices are reaching out to where and how frequently, custom block lists, custom local DNS entries, etc).
As a satisfied customer, I just recommended their adblockimg DNS on here a few days ago but am happy to do it again. If you really don't want to install anything, at least adblock at the DNS level. https://adguard-dns.io/en/welcome.html

That's the intention of intermediary liability laws - to make meritless censorship be the easy, no-risk way out. To deputize corporations to act as police under a guilty-until-proven-innocent framework.
