These risks are not different from before and still open source has the advantage of being open to anyone and any agent.

Kernel modules written by US employees with unknown ties to US intelligence was just as much at risk for containing a backdoor as if written by an agent using an LLM with US intelligence ties.

And in both cases intelligence actors or security researchers from around the world can review it all and try to spot backdoors. So can agents with different LLMs behind them.

It would be an issue if there was only one state sanctioned LLM available, but as long as there is world wide competition in training LLMs, opensource will be “reviewed” with competing interests in “mind”.
