Ha, possibly, but that would make them poor "winners" as I remember, we lost that one. I think they do it just to terrorize us old gringos, but they have made a concession, for MX citizenship the need to speak Spanish is waived for gringos over 60 (they figure we're just too darn old and dumb to learn?).
You do have to think twice, a couple years ago I was walking through WalMart and saw a little netbook for a good price and tucked it under my arm - well, duh, you're in MX, the OS was in Spanish, the keyboard is in Spanish - and yes, there are differences, they don't have contractions, so no apostrophe key etc.
