FWIW, years ago, some people who worked for a political think tank approached me for expert input. They subsequently published a report that cited many of the sources I had mentioned, but their recommendations in the report were exactly the opposite of what the cited sources said (and what I had told them myself). As far as I know, there was no GenAI at the time. I think these people were simply betting that no one would check the sources.
This is not to defend the use of AI, on the contrary - I think this shows quite well what sort of people would use such tools.
