What if this other Other group, if they exist, were powerful in some way
that Ben's team is not, could manipulate them in some way, or could appear to be invisible, listening in. Who knows what this other group is actually capable of?

It might not be a matter of allowing them to do what they do, they might not have a choice or be able to catch them in the act!

Could they be the "whispers" we've heard throughout the series?

Frank: No, the worst.
