I was going to write up something about the original post but this hits the nail on the head.

I would also add that the idea the Crafts are an "obvious author favourite" is heavily undermined by the fact that M20 presents them decently neutrally. Metaplot options include the Disparate Crafts being 100% incorrect about the whole Nephandi thing, or their belief that the Technocracy and Traditions are run by Nephandi might actually be a Nephandic plot! "Isn't paranoia fun." The book is upfront about their good and bad sides. We're shown that they stand up for downtrodden...
