It doesnt sound like they were choosing the most right-leaning perspective, but rather the first on the list (the one that would play after your current video finishes if you have autoplay enabled).
That Jordan Peterson video was in the #4 position in the sidebar from the Musk interview. However, it was the first video that did not include Joe Rogan. So far so good.
Thereafter, clicking the first recommended brought me to another Peterson video, then Gordon Ramsay, and then into an endless loop of Kitchen Nightmares clips.
Certainly, there's some stochastic element here, but I'm still not convinced.
