@elrido Woah, long reply… way too long 😉
Trying to address them:
1. DNS censorship: Yes, this si exactly what this protects against. Even stronger, because DNS cannot be manipulated.
(also AFAIK many OpenNIC servers are not hosted in the US, but that's off-topic.)
2. Internal company services + webdev (host entries): Yes, it can fallback to resolving these, if the DoH provider does not resolve it. (Currently, that's even the default.) Already discussed here BTW: https://metalhead.club/@kromonos/101840600370718191
