They also refuse to actually show the parameters you searched for. If you sort by “upload date,” the first few videos might be more recent ones by upload date, but anything past that you’ll find a video that was uploaded five years ago, then five months ago, then three years ago, etc, which—NO! That’s NOT WHAT I ASKED FOR!! PUT THEM IN ORDER!!!
Also sometimes the “people also watched” bullcrap will not only be entirely unrelated, it will also be videos with violent, sometimes outright triggering thumbnails. I’ve gotten some AWFUL unrelated video thumbnails just when searching for video game music videos.
