I still think that Megatron is the real boss of TRF, and that TRF is gathering and organizing the numerous Decepticon forces coming to Earth for Megatron under the guise of a "prison." It said that Lennox had doubts about the organization he was working with, and Megatron being revealed as the boss would definitely confirm those doubts. We have only seen TRF personnel and equipment fight Autobots and human protagonists: Bee, Cade, Canopy, Izabella, and Dinobots. Some people claim TRF was looking for Canopy's Decepticon "badge," but if anything that shows that TRF is distinguishing between the factions for some reason. Why? Because Megatron is using them to kill Earth-bound Autobots and gather Earth-bound Decepticons. To Megatron human-built machines, whether it's KSI's prototypes or TRF's drones and mechs, and humans with anti-Autobot sentiment in TRF would be the ultimate cannon fodder serving him, because he could care less about how many are destroyed by the Autobots and human protagonists. Not saying it's definite, but it's my theory.
