Shatner,

As per PRNewswire - Companies that hire PRNewswire to create a press release don't want PRNewswire to rank higher than them. I don't have a problem with duplicate content on PRNewswire being hit by Panda. Also, I have seen spam on PRNewswire. Basically, it is all about promoting your business.
