Uh. I thought it was all about parasitic currents. Strong enough EM fields induce those in the wires, brain gets stimulation and goes into seizure, this sort of stuff.

(Neighbor comment[1] suggests those devices don't have anything like firmware upgrades, so don't see why they need an actual receiver)

That would be the obvious interpretation, yes. Induced currents from EMI can be dangerous, and implants don't necessarily have the luxury of shielding, but if that was why... then how would encryption help?

I'll fully admit I'm speculating. It just seems odd.

You don't need to intentionally create a radio receiver to inadvertently pick up EMI. Simple thin wires will end up with this same parasitic current problem, by nature of their shape and composition.

Shielding around these thin wires can be impractical in many situations due to the limited space afforded by the brain and skull.
