That was my initial assumption about how they're collecting the location data too. However I find if I switch to a different browser it will rarely mention my location, so it could be finger printing and pulling in info from previous device session where I have mentioned my location.

I think the larger issue here is that when you ask how it knows these things it seems to have been instructed to lie and say it doesn't know and has just guessed which seem extremely unlikely. This simply isn't acceptable in my opinion.
