The moment I saw this pop up on my screen, all I could think of was the destruction one could cause via fake alerts. For instance, a warning of incoming nuclear warheads like what happened in Hawaii a few months ago. Sure, news stations might rapidly debunk it, but how many people wouldn't see it? Cell towers would be overloaded with calls and data, preventing the dissemination of info to many. Radio would be the best bet, but how many people would go out to their car (likely the only place they have a radio) when they think an attack may be imminent? A centralized system like this seems like an extremely dangerous thing to have.
