I'm not so sure about that. I mean, maybe not since the Snowden leaks but how do we know that governments haven't been running their own LLMs for the last five years or so? We know that they're using sockpuppets[1]. We know that they're astroturfing[2]. Integrating LLMs into their toolkits seems like an obvious move, so obvious that they would be stupid not to do it.
