They are paying for the light too.

  But using the overspill light doesn’t reduce the availability of light.

      But the point is that someone is paying for that bandwidth to be available, regardless of it being used or not, at the moment. Light is not consumed, it is produced. Someone else put it that spillover light is gleaned. Bandwidth cannot be gleaned in the same way. You don’t have excess bandwidth like you would have light.
