>Conversational ads embedded in AI responses blur that line to the point where it may not exist anymore. When an AI tells you "Product X might be right for you because..." and that recommendation is a paid placement, the disclosure burden is fundamentally different from a blue link with "Sponsored" next to it.

If you look at the videos in the blog post there's clearly a "sponsored" tag next to the sponsored results. I don't see how it's different than sponsored search results.
