They did actually mention multiple times yesterday how they strive for historical accuracy.
The problem with that kind of statement is whether or not they're aiming for accuracy on all fronts, or just trying to stay true to certain basic things like how guns looked, acted, the settings themselves, while taking artistic liberties with others.
If they came out and said "this is going to be a 1/1 adaption of WW2" then yeah I'd see a problem with trying to revise certain parts to fit with modern views.
But "historical accuracy" can mean many things, and be selectively enforced. I don't think it had to be an all or nothing situation.
