Yes. They have taken the highly unusual step of expressing an opinion on the DNS system.
> That makes no sense to me, I thought they were highly conservative bureaucracies heavily influenced by national government
They are extremely conservative, which should add to the weight of this action. However they answer to their respective memberships, not governments - despite being "regional" registries they stay out of geopolitics for the most part.
With this request, I suspect they are more concerned with ensuring proper processes were followed within ICANN rather than the outcome. I think they are primarily concerned with maintining trust in the wider "Internet governance ecosystem" (that they are a part of). This is a concern as there is greater pressure from governments that want to make the case that the current model is not working and should be reorganised along UN/ITU terms.
Does anyone know anything about the NRO's goverence, on paper or in practice?
