This sounds like a great sob story but it's more like "people who aren't competent to run an ISP attempted to cut corners and encountered the inevitable consequences".
Or it was people who weren't going to be served by commercial companies tried to help their community as best they could on a shoestring budget, with minimal funding, in a non-profit fashion.
If you're trying to do an ISP on a budget, IPv4 makes things harder.
The fact that they did try to go ipv6-only (ie. "cutting corners") shows that the people involved were blamed were incompetent.
That explains why cellular ISP are progressively adopting 464XLAT, a IPv6-only technology. /s
