There is nothing special here in terms of data. I've worked with the Youtube API before and basically everything that's displayed on this website is easily available there (as long as you snapshot it, which it looks like they started doing in October this year).
I think the only thing they are doing here that I haven't seen on any competitors website is the differentiation between shorts and normal videos. Last time I checked, there was no reliable way to detect whether a video is a short via the API, so you either have to build ugly heuristics for it or build a scraper that tries to access the video as a short. I think this might be quite valuable as the introductions of shorts has disturbed view numbers and accordingly channel/audience valuations quite a bit.
Per-video analytics are also not something that's freely available on competitor platforms IIRC.

Correct. This is what they say
We use a combination of channel performance along with detailed video performance history to break down longs versus shorts. If you'd like to learn more, please contact our team at...
Why would he have any pull to make Youtube do anything? What's he gonna do if Youtube refuses, stop using Youtube? He needs them much more than they need him.
