Thanks @cadadr for the link.

Control access point inclusion in Google's Location services - Google Maps Help

To improve Location services and estimate the location of a device, Google uses publicly broadcast Wi-Fi information from wireless access points and GPS, cell tower, and sensor data. This data is limi

Imho it should be a confirmed optin. Something like ending with _googleisallowed.
@hans Unfortunately, when Google managed to convince the general public that they want to be watched, it wasn't by obtaining their informed consent first.
I know, but I live in Germany :-)
@kakure For something like that to be effective in, say an apartment complex, I’d bet everyone would have to add _nomap otherwise there’d just be one less ssid
@kakure @cadadr isnt it completely against GDPR ?
@fatuus I suppose it is up to debate whether data about a Wi-Fi access point count as "personal data".
@kakure I'm going to start indexing wifi names unless they put _lolmap at the end of the name, now.
@kakure @cadadr I will record everyones location, if you want to opt out please change your legal name so ur name ends with dontmapmepls. -joke
