Ah yes the old "our game isn't shit! it's just too deep for you to understand!" Defense.
They're trying to tell players to make their own fun, except that only works in open world games like Arma and Rust because their PVP focus makes them endlessly replayable.
You have players doing this by roleplaying or amassing loot and not turning it in so they can defend it, but that only goes so far with the barebones game they have. You can't interact with the world at all except by walking, sailing and shooting skeletons. Even DayZ has more to do and that game is dead.
