through no fault of mozilla's, most home routers are ridiculously, pathetically insecure. this is not a situation that would be improved by making it easier to geolocate routers from specific vendors. if vulnerable routers become easier to find, my communications passing through that router could quickly become a lot less private. would mozilla be responsible? no. but that doesn't mean mozilla sharing my probably-vulnerable router's location wouldn't play a role in compromising my privacy.
