I don't think anyone really knows the true nature of Cybertronic's leader.
On the second question, the answer is "yes and no." Yes, you can "be a Freelancer." But you are never really free because you rely on Cybertronic to get you your drugs and repair your body. IMO, a Cybertronic Freelancer is a Cyber on very detached, independent duty.
