Conservation of Rotational energy is not the same thing as conservation of
angular momentum, The angular momentum is conserved because there is no Net
external Torque, the energy is not conserved as an external force is acting
through a distance, in particular the tension applied to the bottom of the
sphere, additionally the PE due to gravity of the sphere increases as the
sphere is collapsed

so not Tom-AYE-toe, Tom-AHH-toe.
