Looks like an open version of SkyHook from way back in 2003: https://en.wikipedia.org/wiki/Skyhook_Wireless

For a while they had a paid program, I had a Windows Mobile app I could run with an external GPS dongle that would record wifi APs and location, upload to skyhook, who would occasionally cut me a check for my trouble. I made tens of dollars!

I started rotating my BSSID weekly after I learned Apple and Google abused it to track the location of people and devices.

Permanent hardware or software IDs, such as the Windows GUID or machine-id on Linux (systemd) are inevitably abused for surveillance sooner or later.

Isn't this just wha WIGLE does?

Apple says you can opt out of this collection by appending _nomap to the SSID:

> The owner of a Wi-Fi access point can opt it out of Apple's Location Services by changing the access point's SSID (name) to end with "_nomap." For example, "Access_Point" would be changed to "Access_Point_nomap."

Worth noting that the coordinates for cell towers returned by the WLOC API are coarse enough to be just about useless for locating towers. For APs it’s much better but still not great.
