I’m no tech builder. But removing my output from a corrupt and vampiric system does objectively remove some energy from that system, weakening it (albeit imperceptibly). If this was done en mass then that system would be affected.

Pull up the map & have a look at that spot with no light at all, the last attempt to build a road & all before it slid down the side of the cliff shortly after they built it, they don't have that issue & won't unless they actually draw enough attention to make it worth the effort.
