This is not mapping free WiFi hotspots.
This is mapping open Wifi hotspots.<p>They are not the same.<p>For example, KPN in the Netherlands is not free, and xfinity wifi in the USA is not free.<p>For this to have any sort of credibility, there needs to be a discriminant filter mapping truly free vs open hotspots.<p>For me this current map is too noisy to be of value. Try using it for free internet, and you too may run into disillusionment and frustration.
