While I agree that I would like to see more lore delivered in-game, both actual information (military, scientist, politician, etc.) and also the sensational part-true word on the street versions (newspapers, politicians, survivor notes), I don’t agree that we really need “backstory” on the companies involved.
Let’s face it, here in the real US, you can find countless brands of everything - guns, cereal, cars, computers, etc. They don’t come with history books for their manufacturer. We take these brands for granted. Who here can, without looking it up, tell me anything about Chevrolet, Boeing, Sony, Black & Decker, Colt Manufacturing, or General Mills other than “what they make”?
