I don't care about the multiplayer. Multiplayer CoD (or mainstream multiplayer FPS in general) have long since foregone the notion of recreating the context of the battle and are way more about just a fun multiplayer experience. So yes they should absolutely allow more customization in ways that players like. Extending that from the hats/emblems/skins to character gender and race seems like a natural evolution that makes sense.

It still doesn't make any sense why they would change the single player story symbols. Even if there was an audience of people who really want to play WW2 games but are triggered by the Nazi symbolism (and apparently only the symbols, not anything else like the war stories or environment/aesthetics or language/word choice or character interactions) this feels like a weird message they're sending. That apparently their rated M WW2 game is "for everybody!" Even people who have extreme reactions or unpleasant associations with WW2 and the Nazis. Which just makes no sense to me.

It's like if someone made a violent horror game but then took out the blood because they want players who get freaked out by blood to be able to also play their game. Dude, you're making a violent horror game, those people don't want to play your game to begin with. You're not going to somehow get the PTSD war vets to your WW2 game by taking out the Nazi symbolism.

We'll never know, but I would be shocked if this decision somehow got them more sales than if they just kept the symbol normal (at least in SP).
