The outrage some people have is odd because it's anologous to wanting 2D isometric view games. If that's someone's preference, they can still find such games, either old ones rereleased or perhaps some indie titles. However, I doubt a major dev and publisher is going to create such a game today, so it's better to either accept today's gaming evolution or stop playing (or at least stop playing major releases).
There's nothing wrong with having a basic, set background because, as Todd points out in various interviews, it allows a better story development for writing events and (in general) allows players a better reason to feel some empathy and attachment to the PC.
I've explained various times why FONV and The Courier is not a good example of storytelling and why that game fails in general as far as writing is concerned. Sure, some people can like it and that's fine. Some people love teen slasher flicks, too, for example, or even big budget blockbusters like Avengers, but you won't see such films winning Academy Awards for their well-written stories. Not that BGS games will probably ever have award-winning stories, either, but most Western games wouldn't because that isn't their focus nowadays and hasn't been for some time.
For the record, I almost certainly won't feel much attachment or empathy unless I can create an adolescent girl with my preferred visual aesthetics for design. I have never been able to do this with any of the games by Todd's team until necessary mods are available, so I am hopeful that such mods will happen again. I can still play the games, of course, but there's no emotional attachment unless I can create a character I can identify with. It certainly isn't true that a player can "make whoever you want and do whatever you want" so I really wish that Todd, Pete, and others at Bethesda would stop making that claim with their games. For the vanilla games, other aspects than emotional involvement make them worth playing or at least checking out, so I anyway while I wait for my needed mods. I don't see FO4 being any different in this regard.
As for the story writing specifically regardless of PC presentation/options, BGS has god story writing for the type of games they create (i.e., within the top priority restriction of being open world without being forced to play one specific character that isn't of interest to many, many players such as Witcher). BGS will never have writing and/or emotional connection to PCs that match the level of Japanese visual novels and adventures, or various RPGs such as Phantasy Star, Star Ocean, Xenosaga, etc. That's okay, though, because the focus/priority is different between such games regardless of them all being RPGs at their core.
