Properly shielded equipment uses different methods to 'break the cage'. It's been many decades, but some of the heavily shielded designs I did in the 80's involved opto-isolators. Yes, that's right. Want to avoid radiating information ? Use light.

this used to make sense to me, but now that I understand that light is just part of the EM spectrum, I find myself confused.

What is the sound of one hand clapping?

Massless particles travel at c in their local frame of reference, always. Having mass in the way just makes the path it takes longer. The researchers who "stopped" light trapped it inside a crystal, while it was "stopped" the energy existed as excited atoms inside the crystal.

From an outside perspective light can appear to be propagating very slowly, but from the perspective of the photon it is always traveling at the same speed. In this vein though, I wonder if it's correct to say that light propagates instantly and we only observe a time dimension because we are traveling through time.

hm, they should make a movie about that
