It's not just a Citadel DLC issue, but why the hell does BioWare keep giving us armors with Cerberus livery on them?

It's especially annoying when you know there are Alliance equivalents worn by your squad mates in game. WTF? I understand that some PC players mod their games to fix that, but I'm not going to buy and replay all three games just for a stupid armor texture, am I? Why BioWare, WHY?
