It's possible to interpret what Cahcuia said that way. She said their existence was unnatural. Plus since this is the IX expansion, it's entirely possible this process was similiar to the Iifa Tree, which was preventing the souls of Gaians from returning to the crystal.
If I am remembering right the goal of the Terrans was to harvest souls from Gaia and use them to revive or fill the soulless people that are left on Terra. This would seem similar to the endless which as I understand it need souls harvested from living people to then be combined with their memories to then exist in the Living Memory. So I guess technically they do have souls, but it is the soul they took from someone else who is now dead, and with the way things have been going probably killed to obtain that soul.
