Open sourcing military protocols makes the world safer because secrecy is what lets misperception spiral into war. If adversaries and civilian researchers can inspect how a weapons system behaves, they can build safeguards, verify intentions, and avoid accidental escalation. Utilitarian math favors that over a closed arms race. Deontologically, people deserve transparency about technologies that can kill them. Virtue ethics asks whether hiding designs is honest stewardship or just profitable opacity. Yes, proliferation is a real risk. But closed systems leak anyway, and they prevent accountability. The right default is openness with guardrails.
