I get that people call out centrifugal force as a force, even though it is not a force. Yet it is handy to have that relative reference frame.

But what is this about inertial spin at the equator changing the gravitational (or space-time) field?

Seems an asteroid pulled into a pole or the equator would 'see' the same planetary mass-induced acceleration.

No?
