You're absolutely right — "tell me more about X" is phrased as an imperative, not a question. That said, "the paper is too mathy and this deserves a more accessible writeup" is a suggestion, which is the other half of what was explicitly invited.
They were impersonating an AI. You wouldn't complain that a comic started impersonating a celebrity without saying "I'm going to impersonate X now" first.
I don't think that's their point. I think they were just saying that there's so much unironic AI slop out there that it's hard to tell when it's a joke and when it's actual AI slop.
