Huh. I thought perhaps it was the usual "why are all the recommendation algorithms showing me gay porn?" class of complaint, but I went and logged in and it seems that he's not wrong though the degree seems to vary. I've got a bunch of these but also a bunch of outrage bait and generic general stuff. I think if you don't use the platform you get the undifferentiated high-engagement stuff which is likely the same as those Taboola chumboxes that people have on their websites.

EDIT: Hilariously, I went there 45 minutes later and I must have interacted with something because now everything is posts about football (along with the "i want an argument with my husband" post!). I'm in the Bay Area Gooners group but that's been over a decade, so presumably what happens is they don't run recommendations until someone shows activity. Just logging and browsing the feed must have triggered it because I didn't see any football stuff last time except BAG.
