That doesn't answer my question: You astronomers knew (and
complained!) that UTC was unscientific when leap seconds were
introduced, why then did you start to use it ?

And having done so, why do you complain that the rest of the world does too ?

And in this you are just plain wrong, as demonstrated by facts on
the ground: A lot less than 1% of the planets population use a
timescale which are within a minute of mean solar time.

Civil Timekeeping is whatever time the politicians decide.
