Problem again, is centralization of LLMs by either the governments (and they always act in your best interest, amirite?) and corporation, which Non-FOSS LLMs prevent.

Democratization of the models is the only way to actually prevent bad actors from doing bad things.

"But they'll then have access to it too" you say. Yes, they will, but given how many more people who will also have access to open LLMs we'd have tools to prevent actually malicious acts.
