Whilst this is a very valid view, I am not sure there is evidence for it, if you have it please do provide it.
It is not obvious to me that one credible citation is better than having appeared many times in the training data.
Also knowledge releases of models are too slow to be depended on for marketing in my view. It is the search / retrieval of LLMs for which one can optimise.
A final point would be that none of this changes the point made, which is that there too much noise due to too many products being shipped.
AIs recommend what is most popular/well-known, which isn’t necessarily what is best. Both your description of AI sourcing and your AI-written comment demonstrate this point.
