In a meatspace casino, if someone shows you 4 face down cards, asks you to pick one, and then turns them all up to reveal 3 prizes and 1 "you lose" card, you can be fairly sure you had a 25% chance of losing.
If the croupier used sleight of hand or secret e-ink cards to turn your card into the "you lose" card after you'd picked it, that would be fraud.
The dark patterns and dopamine manipulation are bad enough, but isn't it fraud in this case? They're using a visual metaphor that is a straight-up lie.
