For what it's worth, Cablevision already offers FREE WiFi across parts of Long Island. The SSIDs on the WiFi stations also advertize Comcast's Xfinity and Time Warner SSIDs with the intent being that if you are a Cablevision/Comcast/Time Warner subscriber you roam for free on the other MSOs network.
What the article is probably not saying is that service will be free for subscribers of Time Warner and Cablevision (And probably Comcast) but people without subscriptions will have to pony up a dollar for a day. For people who travel internationally, a dollar for a day's worth of internet access is very cheap.
And the terms are still being worked out on this....--
-Stupidity, like hydrogen, is one of the basic building blocks of the Universe.
-Insanity: doing the same thing over and over again and expecting different results.
