I can detect a cablevision, a comcast and a timewarner hotspot at my Dad's house in Yonkers. I doubt that CC and TW have set up their own infrastructure there, so it appears that this was unofficial policy in the past.
It's all the same hot spot...just serving three separate SSID's. You had to connect to the right SSID for your cable provider in order to authenticate. The article implies that all authentication has now been unified.
