I don't remember where I saw it but there was a woman in one conference who very eloquently put it that since frontier AI companies took humanity's work to train their models [without explicit permission of every single person who contributed], then those models belong to all of us and should be open. I think it is a very grounded perspective.

And I agree that LLMs themselves are harmless, it's the people behind them driving the agents and instructing them to do bad actions are the ones posing harm. But if the models were open and everybody could operate them on equal grounds, then the good guys would have the means to fight back against the bad guys, in a very simplified sense, just like they did before the LLMs. Everything stays balanced, just both sides get faster.
