Maybe I’m naive, but I see this as a coincidence. If it was an hour later, then maybe there would be something.
I don't see the publication of a marketing page (again, not a finished product) for a product founded by someone who's other main venture is being investigated by journalists for misleading claims as being a coincidence, but if the timing matters and 14-15 hours doesn't seem like it works for the assertion in your mind, then perhaps the Dall-E 2 page going live less than an hour after the Worldcoin HN submission fits the bill.
I've got no horse in this race. I'm just drawing attention to familiar PR strategies used for brand risk mitigation, that's all.
