You really think this would even have live long enough to write an article about it if it wasnt built properly?

This is not a new concept, its been around since 2014 so they will just have copied a lot from existing projects like the german freifunk which i participate in (exists since 2003).
NYC Mesh has been around for more than a decade. I assume they talked to other similar projects when building it.
