So blocks are just happening on public open resolvers and not on the TLD servers? What's stopping people from standing up their own DoH servers? It only takes a few minutes. Install Unbound and see if it was compiled with libnghttp2. If not then it will need to be rebuilt. Politely ask your package maintainer to also build it with libnghttp2.

    unbound -V | grep --color libnghttp2

If so enable the DoH listener [1][2]

DNS4EU have also blocked archive.today in the past. I i remember correctly, they claimed it was part of some automated malware-protection system. So i would give them the benefit of the doubt on this one.

In any case, plenty of other free EU DNS services available: https://eualternative.eu/categories/public-dns/

So the 'privacy first' resolver doesn't follow only laws, but the whims of any 'government authority'.
