Yes.  It's part of an evil plot.  You almost have it figured out.

My 2001 bought way back when came WITHOUT cruise control. I added it
myself from Toyota upgrade parts and never regreted it.

Think about it a little bit more.  As has been said here many times before
the Prius is a gas-engined car with electric assist.  This has (as we say in
the UK) sod all to do with cruise control (as far as I can see).   Cruise
control is about selecting a road speed and then controlling the "throttle"
to maintain that speed.  In which case it could just as easily be applied to
a steam driven vehicle.  How the control is achieved is the key.  As the
Prius has a "fly-by-wire"  throttle, control is probably more easily
achieved than the steam engine, but I don't think hybrid technology has the

I am open to educating, however.......

I would think of the Prius as more an electric-drive vehicle with a
gas-engine assist since the front wheels are driven by the MG2 electric
motor and therefore are not powered unless MG2 is operating.  The
throttle for the Prius gasoline engine is always controlled by the
computer which also monitors the road speed so the cruise control
elements are already included on every Prius.  However, I investigated
the cruise control 'option' for the Prius and it was not even available
for the 2001 first generation model for which the only options (in the
U.S.) were a CD player and floor mats.  The 2002 and 2003 models (also
first generation) had cruise control available only as an option.  The
second generation Prius beginning with the 2004 model had cruise control
as standard equipment for 2004, 2005, 2006, and 2007.  For 2008 and
2009, cruise control was included as standard equipment in the 'touring'
model but not the base model, although it is included in all of the
options packages and, as a practical matter, almost every Prius comes
with an option package.  However it is theoretically possible to buy a
2009 Prius without cruise control.  So...I was wrong to state that every
Prius has cruise control, but only like 99 percent of them.

This is not correct. You seem to be thinking that the Prius is powered
something like a diesel-electric locomotive. Power to the wheels can
come from any or all of the gas-engine, MG1, and MG2, under the control
of the computer. For the Prius, cruise control is simply another input
to the computer, which decides how to provide power or braking to the
wheels depending on the car speed, and settings of the accelerator or
brake pedal, gear selector, etc.
