Yes i bought the DLC and oh my god are these things overpowered! The rewards are stuff like 50% manufacturing all worlds, 50% influence all worlds, 50% range all ships etc you get the point plus 3k plus credits. I mean it's at the point why take 20 turns to research manufacturing +10% when you can stumble upon 50? There's also bloody hundreds of the damn things! It's utterly insane.
