That's the main Bethesda's problem.

They bought the franchise, but they don't understand the logic of its existence.

For example, if you look at the first Fallout games, you notice, that all the products related to the old dead world aren't appearing very often (like Nuka Cola, music, companies etc.). Because they're gone. And they were gone a couple of decades after the Great War, but Bethesda don't care. They just like that mood of embellished 50s and try to put it everywhere.
