No mention in the article of using powerlines for communication. Shutting down electricity to a population tends to rally people against said government, forcing hard choices on a tyrant: either leave up that communications avenue, or else alienate everyone by cutting off power.
Also, no mention of mass print communications (read: newspapers and pamphlets), both of which are considerably more difficult to police and shut down...and both of which are commonly used in wartime for propaganda dissemination.
Educate pls.
