Some people are just bad at giving interviews. If someone is so bad at interviewing they will eliminate a candidate because they slipped up a little with a programming teaser, they're still going to be bad at interviewing if they try another technique. I'm completely happy doing programming puzzles in interviews myself as I've worked with people that claim to be experts in something when they aren't and some people exaggerate to the point of lying on CVs. As long as you don't penalise a candidate too much for not getting perfect answers I don't see the issue.
