Open-Source Code in the past was fantastic because the West had a monopoly on CPUs and computers. Sharing and contributing was amazing while ensured that tyrants couldn't use this tech to harm people simply because they don't have a hardware to run.
But now, things are different. China is advancing in chip technology, and Russia is using open-source AI to harm people on the scale today, with auto-targeting drones being just the start. Red sea conflict etc.
And somehow, Zuckerberg keeps finding ways to mess up people's lives, despite having the best intentions.
Right now you can build a semi-autonomous drone with AI to kill people for ~$500-700. The western world will still use safe and secure commercial models. While new axis of evil will use models based on Meta or any other open source to do whatever harm they can imagine with not a hint of control.
This particular model. Fine-tune it to develop a nuclear bomb using all possible research that level of government can get on the scale. Killing drone swarms etc. Once the knowledge got public these models can be a base model to get expert-level knowledge to anyone who wants it, uncensored. Especially if you are government that wants to destroy a peaceful order for whatever reason.
