I guess one can't argue with logic that if your network just has one foot of fiber, then it's a "fiber network."
Except that none of these companies are saying that. Cable has had fiber to the node for well over 10 years. They aren't trying to say that they have fiber between 2 routers somewhere in their network.
Why do people keep saying this as if this is what is being advertised?
Even the main article is misleading, because it says "core" fiber, and the author knows FULL WELL that the cable companies have fiber to the node and are not talking just about "core" fiber. Nodes are not the "core."
