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.

We'll see once they pipe ads in there if they'll limit themselves to relevant ads or of they'll toss all pretense of caring out the window
