> how OpenAI is not-so-subtly adopting a social-network-esque model, in how it's fine-tuned its chat system to always suggest another question that the user might want to ask.

Just like the prompt suggestions they added for new conversations a little time after releasing the first app. Those seem to be mostly gone now, at least on mobile.
