Its likely this is designed with a plan to push advertising or self-promotion.

Eg: step one is done - figure out how to both find threads early & get your content picked up as a good answer regularly and consistently. Step 2 - start inserting ‘first hand’ recommendations or even just mentions of products and services.

I’ve already seen webpages with the most esoteric or niche product/service recommendations (like some random Indian consultancy with 2 people listed in it, and no other significant web footprint) pop up in first page web results. Its another AI deathblow to the utility of search engines.
