It's no longer played by the general public. Both rapidly declined in popularity a long time ago.
Not played by the general public =/= dead. If the sites I looked up are to believed, there are at least a million people playing Fortnite right now. Among Us has over 10,000 players on Steam every day and probably waaaay more on mobile.
Why does everyone always say Fortnite and Among Us are dead? Just because something is less popular now than when it was literally the most popular game in the world doesn't mean it's dead. I don't play either but come on, have some sense.
