If technology perfectly reflected people's intentions for their devices, I think we'd see relatively few people deliberately broadcasting wi-fi outside of their homes intentionally and most people's SSIDs wouldn't show up on any dropdown outside their home.

I agree that this information is often available from public places, but I was getting at whose priorities should dictate whether/how the information gets collected and how it's used--people who paid for devices they may not fully understand or be able to control, or organizations that want to systematically exploit signals from them for different purposes that may be different from those of the person who owns the device?
