Nothing is, except the fact that that isn't the way SE wants to write it.

They want the refugees from Doma to teach us their skills. No where, however, do they suggest that the same refugees are the sole source of people bringing Doman Plums to the Grand Companies.

Also, knowledge of Ninjas? Correct me if I'm wrong, but wasn't it said to be a secret art? Just because traders/smugglers/whatever can have had contact with Doma, doesn't mean they'd have an intimate understanding of the place; certainly not of a secret stealth force, and certainly not enough to teach us about it second hand.
