IMHO I don't think digital criminals should be allowed to get away with this kind of nonsense. No better than stealing a bunch of vouchers, showing others how to steal them and then walk back to the store to spend said vouchers.
Creating, selling and distributing cheats is a stupid thing to do. In this case, it is theft (Fortnite Battle Royale is free to play after all and relies on V-Bucks for revenue), and the sale of aimbots and other cheats ruins the game for other players and harms the playerbase, which again has a knock on effect for the developers due to decreased player retention.
I don't see this as big company suing the little guy; they knew what they were doing when they started poking the bear.
