True enough - but 10/100 Ethernet is normally isolated by the
transformer on the Ethernet transceiver.  AFAIK there is not a
connection between the signal lines and ground.  Isolation is 1500V for
the magnetics I checked.

Off course all bets are off when lightning strikes since the voltage
tends to be just a tad higher than 1500 volts.....
