(I didn't understand the math in the paper)

Would this mean that a rotating body in space would eventually slow down? In other words, amplifying EM radiation draws energy from angular momentum?

Yes, it probably even works in total isolation from any radiation, because it can interact with quantum vacuum and give off energy to create photons. That's the next thing they are trying to prove.
