I also get all that you posted.
BTW, "spin velocity" is not the best wording as the spin at the pole is actually the same as the spin for an Ecuadorian (1rotation/day).
Of course the Ecuadorian has a curvelinear path that contains both translation and angular rotation (spin) whereas the Santa has only spin.
IOW- curvelinear translation goes to zero, not the spin.

angular velocity is the same at the poles and equator, instantaneous linear velocity(spin velocity, because the instantaneous v is accelerated into a curve following the arc of the earths surface) is not. At sea level at the equator, your instantaneous linear velocity is ~460 m/s on top of a mountain on the equator it is a bit faster. This is why the preferred orbital launch direction is to the east and the preferred location is a mountain top on the equator, Kilimanjaro or somewhere in the Andes , like Quito
