This then, means that ICE lightning protectors, with their center conductor
at DC ground, are really not good protectors to use? Doesn't it also bring
in to question the advice to connect coax shields to both the top and bottom
of a tower?

To me, what Dave says, answers the age old question about antennas of any
kind: 'To ground or not to ground?".

Unfortunately in this case the 'bleeding' when there is a charged cloud over
head is putting charge ONTO the antenna from the ground to equalize it with
the rest of the charge being attracted to the base of the cloud.  So it make
it MORE likely to start the upward streamer that completes the path.
