One of the major mistakes Hubbard made was to take Scn and turn it into this horrid juggernaut. CofS. It originally was a grass roots self help type thing.
The FZ is like the latter approach, not the former. Also, there are many factions and because it's not centralized, there's no disconnection, there's no expulsions if one comes to a parting of the ways, whether civil or absolutely acrimonious, with a practitioner.
It's really more just people practicing their own personal creed in various ways. It's not really standardized, it's not centralized, it's free form.
That's why most of the arguments against the FZ fall flat.
It was originally designed to be a self-servicing con game, and was later turned into a full blown mind control cult to service Hubbard, the problem starts when people try to rewrite history and claim it was meant to be a form of self-help, the only self it was ever intended to help was Hubbard. The Freezone is little more than a freakshow of people who haven't figured out it's the con game or simple refuse to accept it and want to follow Hubbard down the road of insanity hoping to be the first to reach the imaginary states of Clear and OT
