I believe you can't get anything if there's no official faction governing it.
About tech already granted - due to the new rules once you get something, you never give it back. You see Reavers shooting Corsairs with Tizzles, right? They can't do anything to get their guns back, it's how it is.
Overall, you're in a stalemate for now. You need to wait for a new Molly official faction to show up and give you the guns.
