To opt out of Google worldwide wifi collection you must add _nomap at the end of your wifi SSID
To do the same for Microsoft Wifi sense your wifi SSID must contain _optout somewhere.
So if your current wifi SSID is mysuperhomewifi it is highly recommended you change it to mysuperhomewifi_optout_nomap
Now, I hope there won’t be another “friendly” provider that will require its optingout string at the end of the SSID…
