The total bandwidth used is the same though, no escaping
that, someone pays.

If it was only redistributed locally. Even in that case it's not
helping much as it still consumes the most expensive bandwidth (for UK
ADSL). Transit is way cheaper than BT ADSL wholesale, you're saving
something that's cheap.

Or the caches that are being sold to fudge the protocols to
keep it local but if you're buying them we could have just
as easily done http download and let it be cached by existing
appliances.
