Awwww, but man, I just couldn't resist!
Ya, I understand the thot behind the question, I see there are a few real answers, not sarcasm like mine! But, you got to admit, compared to what goes on around here, that was pretty lite-weight for giving a bit of a hard time!
When I last rode cyclocross - a few years ago (coff,coff) - I rode with clips, and I agreed with the thot of someone else's anecdote here - I felt safer that way.
IMO, the only reasons to not use clips is for "different foot positions" and/or sticking out a foot to drift through a corner. Neither one has much use in cyclocross, and I'm not inclined to agree with an opinion that they are useful for BMX. You can drift without the foot, and if you really need a foot to give you a correction, you probably made a mistake, anyway. The couple seconds you gain from not clipping in are quickly lost down the road. As for different foot positions for managing air, or whoop-de-dos, or whatever, I just can't see the usefulness. It's been a long time since I did anything with BMX, too, so clips may have caught on there. I do remember, back when I was involved in BMX, that this topic was hot, kinda like the helmet wars, and the body of BMX opinion was against clips. However, you also have to realize that that segment of cycling was very much separate from road, or even mountain-biking. There just wasn't much crossover until somewhat later.
Clipping in gave me greater control of the bike, in every situation. If you are using platforms, but with some intermediate system that gives you some clipped benefits, that's fine, it is part of the way back to clipping in, ya?
