What personal info does the location of a hotspot give?
If I look at a map of hotspots all I can glean from is that there is an internet connection there.
I don't know the name of the person who lives there, I don't know their gender, colour, race, religion, I don't know how many kids they have, I don't know their bank details, I don't know where they work. I don't know anything about them other than they have BT broadband.
I know no more about them than I would know about someone driving down the road in a Ford. All I know about them is that they drive a Ford.
I don't have BT internet so I can't use the app but the screenshots shown on the app page don't even show the addresses of the spots on the map. There looks to be a text list of "premium" hotspots with addresses but those all look to be businesses. So, as far as I can see from the limited access I have to screenshots, it doesn't even look as if they're giving away the address.
But even so, an address alone doesn't give me any personal information to work out the name of the person living in that house.
As far as I can see all the presence of a hotspot tells me is there IS a house there - but that's a fact that's already given away the second I can see the large pile of bricks, mortar and glass at the side of the road.
Are phone books still a thing? When I was a kid we had a big book that had everyone's name, address and phone number in it. No one was up in arms about that and that gave away a lot more information than a WiFi hotspot seems to.
The hotspot IS a service, for paid up BT customers. If people don't know they're hosting them then they should read the terms and conditions of their BT contract instead of blindly clicking yes. Not understanding or knowing something isn't the same as not being told something, regardless of how indignant they are when you tell them.
