Semantics.
I don't like to use frame of reference at all because it too is arbitrary to it's own reference point.
If a guy is sitting on a train, does that mean the train is not moving but instead the ground is rushing by under the train? The train wheels don't move the train but instead make the Earth spin under the wheels like a treadmill? It is silly if anyone actually thinks it works like that.
A reference point is meaningless unless it has a comparative. If you leave out the comparative then it all becomes meaningless. I think that is what is been occurring here is a reference to a frame without a comparative.
It gets silly when you do that.
A rock rolling down a hill, from it's frame it isn't moving at all but instead the ground beneath it is doing all the moving. All the rock is doing is spinning in place. It becomes absurd.
When you skydive, your body isn't falling to the ground but instead your body is stationary and the ground is rushing up towards you.
Perhaps people get caught up in this because they are ego-centric thinking they are not acting but instead everything else is acting around them. They are stationary while the ground spins under them and the trees rush by while they sit motionless in a car and the car itself doesn't move instead the ground rushes by knowing exactly where the destination is.
