Economically, I don't think that makes sense. Having a call to action that is just clicking a link is much more likely to be taken than a subtle suggestion. The former will be able to make more sales from the same ad spend which will allow them to bid higher on ads, out competing subtle ads.

Right. Advertisers will still want attribution for their ads. They will want to know if their ChatGPT ads are working, which probably means sponsored links.
