Obviously you don't know much about web directories. Some directories use a feed from Dmoz. Now what is happening is that the rather clueless SEOs believe the Google FUD buddies about "unnatural" links whereas in reality many of them may be reusing the Dmoz data as filler in their directories. These are often not "unnatural" links but because the clueless SEOs believe all the Google FUD about "unnatural" links they spam directory owners asking to have Dmoz links removed because they are too damned stupid to realise that these links are part of a Dmoz feed - that's if the spoofers masquerading as SEOs have even heard of Dmoz. Now if you are differentiating web directories from links directories you may have a point.
I don't know of any link directory that has added links out of their own free will.
