The fact that they invented it doesn't mean they control it. This, incidentally, gives marauds a RP reason to hunt the maraud NPCs - they stole and hold something all the marauders should have access to.
Besides, consider marauders are an organization, not a nation in itself. One is born a fyros or tryker, but one is not born a marauder; from this point of view, having readily-available armor plans does restrict their availability to marauders only, whereas a crafter can learn from all 4 nations their plans. What would happen when the person decides to stop hating, and stops the marauding? Would they forget the maraud crafting plans?
Btw, this has been tangentially discussed already in a much larger thread, which has earned a response from Tamarea: http://app.ryzom.com/app_forum/index.php?page=topic/view/16643/1
