They use regional companies I think, for Europe they use French chocolate (la maison du chocolat).
Luckily for you, there's more games without any loot boxes or micro transactions than you can play in your lifetime.
The problem is these stores (Epic but also the Microsoft Store and Amazon's PC game store) only come along because some executive says "hey what if instead of Valve taking a cut from most PC games, we took a cut from most PC games", there's 0 interest or intent for them to be competition (as seen by the exclusives) for Steam or improve the developer/user experience.
Any time these massive companies offer a cheaper subsidised alternative to any existing product it's to push out the smaller players with less resources and build their own monopoly.
