Its mentioned in the article, but it bears repeating.
They force give you the first quest of a questline for free, and then charge you seven bucks for the second 15 minute quest.
Its also not complete, its an early access paid mod where they clearly cut content out of the game just to give you the first hit of a faction questline, end that first quest on a cliff hanger, and then charge 7 bucks per quest. And before this, the faction was just a series of kiosks giving radiant quests.
