Every WiFi network access point that has ever been in range of an iPhone has its network name (SSID) and GPS location (taken from the iPhone) stored and used by Apple.
Apple introduced a way to opt out in March 2024 - you must append the string "_nomap" to your SSID.

@BradRubenstein That's not what @briankrebs is reporting. He says it's the BSSID. Which is worse, because you can't change it as easily as the SSID.

The issues around this were discussed more than a decade ago in the IETF's geopriv working group. @coopdanger was one of the chairs at the time, and the utter insanity of expecting home users to change their SSIDs to get this privacy was well-explored. That Apple is only now adding this fig leaf of a "better than nothing" solution would be hilarious if it weren't so stupid and sad.
