You’d imagine other broadcasters would be sniffing around.

They have been, but they can't copy the format so are trying to work the treachery angle into other shows in different ways. I'm not sure they will succeed because there's a fine line between deceit and backstabbing and standalone quiz shows where the intent of some people is clear as money has to be won at the end of every episode instead of something long drawn out like The Traitors is perhaps not the best way to go as it becomes repetitive and predictable very quickly.
