BS penalty. Int. grounding on Jameis.

Yea, none of these explanations explains the fact that spiking a ball that is snapped IS stopping a moving clock. Even if the clock is stopped pre-snap, snapping the ball starts the clock. Thus, you're still spiking a moving clock.

I think at this point it's pretty clear that it refers to the status of the clock before the play starts. It's a silly rule, but it seems like it's being applied consistently. It's just clearly kicking a team while they're down. It's not preventing some secret competitive edge to spiking the ball.
