uBlock Origin shows nothing out of the ordinary but Youtube, Google and Doubleclick, so Google, Google and Google, and I assume all of those are due to the embed.

If you mean the block page, yes, that's just the YouTube embed. You'll see the same results on any wiki page that has a YouTube embed for the same reason; it's not tracking or anything I have control over (other than outright not having YouTube embeds). But I think if anyone has concerns over that, they're better addressed at the local-user level by disabling all unauthorized iframes.
