At least when you search for a video topic, you are likely to get a wide range in quality. Regularly surfaced content has a variable amount of dislikes, and almost always the dislike count is signal and not noise.
I rarely engage with YT recommended videos so I can't verify the accuracy of your claims. Either way, however, it sounds like reworking their recommendations algorithm would be a more reasonable way to deal with this issue than simply hiding the like/dislike ratio. How is this change going to meaningfully affect which videos show up as recommended?
- videos with >95% likes
- mostly political videos that have obviously been brigaded
imo this is a reasonable change
