I am betting that joining a Faction is like getting a sponsorship. I'm starting to think that they are all manufacturers of some sort. Maybe they will all manufacture different type of items and having a sponsorship allows you to buy that company's items for cheaper. It could be like Borderlands where there are different manufacturers that imbue their weapons with different recognizable traits.

you have made a point there, we can see that in the photo of the Conduit F3 there is a logo of FWC, or is just a logo you can put in your weapons.

it is part of the FWC faction line but they did mention trading weapons so you get it when you join but you can trade people in the faction
