Dumb q about bb30 adapter cups - are they supposed to rotate/spin along with the cranks?

My old ones didn't but they were glued onto the frame (from what I can tell) to stop them from creaking or something.

The ones I installed (Wheels Mfg) do, and I got some fancy Campy cups that'll hopefully be stiffer than the plastic Wheels Mfg ones.

Anyway I imagine it can go either way, but I'm wondering which way it's supposed to be.
