Because they may well not give a hoot about DUT, or the rotation of that
very poor clock, the Earth.

Almost 1 out of 6 citizens of Earth lives in China, the whole of which has
an LCT of UTC+8h despite apparent solar times varying from UT+5h to UT+9h.
The willingness of almost the whole of North American and Europe to move
a full hour away from its standard time every summer is also indicative,
as are the facts on the ground in Easter Island, whose civil time is
always a good two hours ahead of apparent solar time -- its longitude
is that of San Diego, but its LCT is roughly the LMT of Chicago.
I continue to not believe that keeping LCT at a good approximation to LMT
is all that important to most people who are not astronomers, navigators,
or other specialists.
