I just thought of a possible explanaition. If you implant it through surgery, then they can have the AI active permanently. But if they just jump into their armor slot or whatever, then if they take the armor off, they can't have the AI read their thoughts and stuff. Coz you hear North talk about walking the halls to get Theta to rest, and he doesn't have any armor on and yet Theta's still with him. But as for the people that Omega has infected and Delta has been in, all of them except York have had their armor on the whole time we've seen them. And Church didn't even know the Tucker was black, so I think it's safe to assume that they never take off their armor.

I know it's a long shot, but this is the best idea I've got.
