alt Hacker NewsComcast, one of the largest residential ISPs in the USA, has almost full IPv6 deployment by default. The majority Verizon Wireless is IPv6 by default. Residential customers in the USA have great access if they just enable the stack.
There is nothing about IPv6 that prevents ISPs from filtering ports for all customers. They almost all actively filter at least port 25, 139 and 445 regardless of the actual transport. So I'm not sure "blocking service hosting" is the actual goal here.
The problem seems to be that all of the large and wealthy nations of the world have made the necessary huge investments into IPv6 while many of their smaller neighbors and outlying countries and islands have struggled to get any appreciable deployment.
It should be a UN and IMF priority to get IPv6 networks deployed in the rest of the world so we can finally start thinking about a global cutover.

A UN priority!? They have real issues they should be dealing with like the life and death of millions of people
In many developing countries IPv6 adoption is far and sometimes networks are IPv6-only, because IPv4 is expensive and they have relatively little addresses compared to users...
You can see southeast Asia is pretty green on the map of the post.
