The complaint (https://www.scribd.com/document/490433093/Rumble-Inc-v-Googl...) lists some specific scenarios where they expect Rumble results to show up first: the search phrase "dog videos on rumble", the unique title of a video which was posted on Rumble first, etc.

Even so, I very much share your skepticism that this is actionable or even improper. The idea that it's unlawful for your search algorithm to not translate "on rumble" to "site:rumble.com" would be... quite a precedent.

Funnily enough, while it is true that there are some Youtube videos that show up above the rumble.com video for that query, all of them are from Rumble's own Youtube channel... So they are cannibalizing their own search queries :) And for some loose interpretation of "on", the results are indeed correct, those are dog videos "on" the rumble channel. As you mention, I don't see why it should be a string site: filter, if they're unhappy they can delete their Youtube channel.
