Using a term like 'hn' isn't really a representative example, since it's unlikely that any advertising would be purchased for such a term or have any custom "knowledge panels". So, first, turn off AdBlock (if you hadn't already done so), then try a more representative query like "flowers":

It's a big difference, and these different experiences with Google could just be a matter of which keywords people tend to use (e.g., very general vs. very targeted searches) and what extensions they chose to install in their browser.
