Probably gathered from the app of https://meshable.io/ https://meshable.io/? The website is light on details, but it's probably a commercial WiFi-sharing company, like a commercial version of Freifunk (a mostly german initiative where people openly share their WiFi, and meshing is used to extend coverage when a direct internet uplink isn't available), with the interesting twist that they're using an app instead of a custom WiFi access point firmware. I wonder if they route traffic through open Wifis if any are in the vicinity and then charge for it.
