Honesty implies intent. People can use LLMs to amplify dishonest messages (see: marketing), but I don't think it's reasonable to claim that LLMs are lying to describe when they produce incorrect information against the will of both the creator and operator.
I read it a different way. There's less upside to an LLM being "honest", since they're already making false statements regardless of intent. They're already non-trustworthy. So there's less to lose by being marketing channels.
