I’m really interested in understanding this. So please indulge me... So, I’m Oumuamua rocking my way through interstellar space. I see nothing around me so as far as I know I’m not spinning. Then, all of a sudden I happen upon a solar system that is spinning around me. Who is spinning? Me or the solar system? Is the point here that I’m spinning with reference to my direction of motion?

Yes. You are aware that you are spinning even without external reference because your outer parts are accelerating toward your inner parts. This is the feeling of spinning in a circle on earth too. This is how plausible simulated gravity works too. A ship spins. It doesn’t require a reference to know whether it’s spinning.
