They were not experts that you heard that from.
It is true that there is nothing you can do to prevent a strike but there
is plenty you can do to deal with one and prevent it from doing damage.
Lightning is not unpredictable as many think, as to how it will travel to
ground or what path it will take.
I'd call watching the lightning hit a tower and then get off half way down a
bit unpredictable.<:-))

The only thing that is unpredictable about it is how large of a strike you
will get.

In 1966, I lost a tower to a lightning strike. The tower was a 50ft
Rohn 25 with three sets of two guys. The tower was grounded an the base
with ground rods and heavy guage wire going up about 3-4 ft where it
attached to the tower legs. Unfortunately, the strike went down one of
the guys, over or through the heavy-duty egg insulators to the guy
anchor where it cracked the cement open. The tower, having lost the
anchor point for one set of guys, just tipped over into my neighbors
yard.
I didn't have any grounds on the guy anchor points. I had thought there
was no need, since the guys were broken at several points with egg
insulators. I was wrong. Lightning is too unpredictable to follow
rules.
