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

> DNS4EU commits “not to block DNS resolution except for when required by law, enforceable decision of the competent court or other government authority or elected by the User.” (Emphasis mine)

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