They'd even send one to me .. if I logged into their network. I don't automatically log on to any network that's available. Some people do.

Many people do actually.
Not sure if many noticed but cable companies are making a public WIFI labeled with the cable company name (IE xfinitywifi) available if you use their internet.
It's open and uses the equipment in your home .. I don't like the sounds of that.
Another reason I have my own router for my network...

I do not work here, but the benefits are still awesome
Make your sound your own!
