The Fireflies are complicated
The Last of Us is often very cynical about whether organizations like what’s left of the United States government or revolutionary groups like the Fireflies can appropriately respond to or provide solutions for complete societal collapse. There is a constant power struggle between groups like this in the game. The opening environments set that tone with the obvious attempts to cover up and silence slogans and logos of the Fireflies that have been graffitied on closed storefronts and walls throughout the Quarantine Zone.
As we can see from the trailer, that element is at play here when it comes to the Fireflies, who may or may not even be the “good guys” of the story. People can be seen painting over the “Look For The Light” slogan in a way that’s remarkably similar to what’s observed in the original game.
