Thanks to Matt Pacocha from VeloNews who forwarded me a brief article about the Dugast Diablo ban and all the hullabaloo it’s been causing since Sven’s testing of it in Eindhoven. I loosely translated this article originally found on http://wielrennen.blog.nl/. Molly Cameron also chimed in to me to state that he thinks the ban has been around for some time (still researching that….):

"Cyclocross riders may not ride with spikes or with small nails during World Cup events. The Dutch tire specialist Andre Dugast had a new tubular, called the Diabolo (Devil), made specifically for the conditions for Tabor. Dugast is no stranger to the cycling world, as most of the worlds best have ties to the company and race on their tires. In a first test of the course in Eindhoven, Sven Nys achieved a speed of up to 30 km / hour (!), Sporza reporter Marcel Wuyts says. During the World Cup broadcast next Sunday on Sporza a special segment on Sven Nys’ test of the tires in Eindhoven with be broadcast. 

Nys said in an initial reaction that the tires are phenomenally good. And a phenomenon they will always remain because the UCI has thrown in a wrench. When rumors reached the UCI on the spiked tires, they quickly reacted to ban. It would distort competition because less wealthy riders on the "old" treads will not be as competitive. Well, on an old tape you have to learn it? Seriously, it is not dangerous to life with nail bands around, crossing? Imagine that you are smacked against the floor by, say, a drunken supporter. See how quickly you’ll have to have a Czech doctor to find and pull all those nails out of your body.

Moreover, the Schwalbe tire manufacturer has a much longer relationship with spikes in its product range, but unfortunately for the racers, this involves an ATP band as well":
