I have been searching around a while and i know the "residential vs business broadband" has been done to death. But i cant find any info on the UFB side of things.

Is there some reason that residential UFB is cheaper but business UFB is more expensive than their copper equivalents?

Business broadband get "very little" (i think even that is genorous) for the extra they pay that's established.

And I believe the residential wholesale pricing of UFB is cheaper than copper. This is why UFB is often cheaper than copper.

Is the wholesale price for UFB different for residential vs business?
Is there some kind of government subsidy that is applied to residential and not business?
