Zoomcorder ad on webinar registration page

I recently scheduled a webinar but on the registration page an advert for Zoomcorder (not a Zoom product, as far as I can see) has appeared - see attached screenshot. I haven't seen this kind of thing on other registration pages that I have used.

Can I delete this or is this just Google/Google-style advertising built into the registration page? It seems strange that Zoom is enabling advertising for a non-Zoom product! Many thanks!
