Just a thought, but maybe they've done it because the concept for both programmes originated in the UK - and this was a condition for allowing them to franchise the shows?
I know that Simon Cowell 'owns' a percentage of the idea for Idol - and franchised it to the USA.
If the chef you are talking about is Gordon Ramsay (don't know as we don't have the USA version) then he is a GREAT chef. His restaurants are Michelin starred and I've eaten at his places on a number of occasions. If he IS the British chef, then he's opinionated - but with good reason. And yes, he SWEARS a LOT.... BTW, he's a Scot, like me
