TLDR: This is what Paywalling is, and the more you support it the more publishers and developer think this practice is okay.

I'll start off by saying that this service is awesome if you want to have your own private server for grabbing world scrap, finishing quests and raids with as little latency possible, infinite storage of strap you need, Extra atoms to spend in the stop without paying for single packages, and a survival tent you can pretty much place anywhere and travel for free.

That all being said this practice is Predatory as all can be and here's why.

You will most likely purchase this if you are a long time player because it gets extremely difficult to keep the aid items, weapons, armor, and scrap all together in one place unless you are super particular. You will purchase this just to give you some breathing space in your stash box.
If you want more stable game play because the server is too full, you're trying to farm specific items but they're all gone because a player took them, or you're trying to do your story quest/raid without issues of latency. You will purchase this for that private server.
If you're sick of paying caps to travel everywhere, you'll purchase this for the tent and cool skins. Luckily for you too, you have a mobile stash point and a scrap box so you don't have to walk all the way to somewhere to manage your inventory.
You get atoms to spend in the shop! You can make your camp look cooler than anyone elses with those "free" caps. But since the story only has a "Limited time" for you to purchase those cool items, you'll most likely spend them fast to get the item so you dont miss out only to find out that some even cooler stuff has released a day or week after. And since you spent those atoms, you most likely will buy more.

All in all, this is a business model you should not support in any game let alone a AAA game. The odds are stacked against you. Think about the situations you encountered in game and how easy it is to Just buy it. Please be responsible for your purchases.
