Why? If the voltage spikes on the grid (that's what I understand a power surge to mean), wouldn't even more of it end up in your house (that is: the grid voltage spike even higher) if the neighbors have equipment that doesn't let their devices consume some of that energy?
Edit: wait, maybe I figured it out: those devices must be consuming the excess rather than blocking it. Is that it?
