Do residential subscribers provide a "TWCWifi" hotspot?

The stuff I've read from TWC say that the hotspots are provided by business and other

public spaces.  My question is this - under what circumstances do private residential

subscribers provide a hotspot?  What is the association?

Residential customers show up on the coverage map with a blurred blue

dot.  Here, for example

THanks for any info
