Honestly no idea. They just don't. Growing up the only fish we really ate was fish sticks and heavily processed fish cakes. When going out to restaurants I have no real memory of anybody really ordering fish. Even when I was living in down town Oslo (admittedly 20+ years ago), just getting ahold of fresh fish was hard. The only food store that had a fish mongers and sold fresh fish was the really fancy store in the most expensive part of town. There were maybe two fish stores in all of central Oslo that I knew of, one of which was a high end luxury food sort of place that also sold fancy caviar, foie gras and oysters. Compared to basically any costal town anywhere in Europe where fresh fish is plentiful and ubiquitous, it is really strange.
That would probably be point number 2 in your list. West coast and northern Norway eat a lot of fish/seafood. Also within the last 20 years sushi has gotten a lot more popular here, even around Oslo.
