The ignorant author apparently isn't aware it is not the
unhealthy hollow
oaks that are the greatest threat to falling and causing
damage. It is the
top-flush large trees that catch wind and and are literally
thrown over
because of their short roots.

And the fact that they are top-heavy. These kinds of trees are
common in "wooded" lots around the USA. These lots USED to be
forest, so the trees are tall and slim, with all the foliage at
the top -- where the light USED to be. When the forest is
cleared, leaving one or two "specimen: trees in the lot as
"amenities" you have a few large-boled, heavy-topped, "popsicle"
trees (NOT the shape you'd choose as a bonsai) that whip around
in a stiff wind, eventually loosening the roots (which were
relatively small because of all the competition with other -- now
rotted away -- roots in the former forest.
