It's been some years that I am not able to log in to my Google account, because I stopped using it for a very long time any Google product, and now even providing my password, they say they can not know if it is me or now...
They send me to this support page which seems like I have lost my account with all the data and stuff I had from when I was younger...
I don't think this is normal or ethic to do (I know Google has been never ethic), but this makes me so angry because I never wanted to lose all that data...
Do they basically know every people networks? And if you don't let them know... you lose access to Google? ... ๐
Well, in a way, they do provide accurate geolocalisation for indoor environments based on wifi networks. And it is right that having internet/bluethooth access also (more or less) reveals your location; but that doesn't make it ethical.
You are thinking of https://opencellid.org and of Mozilla location services. You can contribute to them with the TowerCollector app.
UnifiedNLP is just one interface that can use many "backends" or "location services", like the Mozilla one, an offline list, or even google itself via microG.
