The Youtube rating system is an absolute joke and does not give any feedback or information whatsoever. Hardly and Youtuber if any has ever legitimately been harmed by dislikes, they only boost their videos in the algorithm and get them more views and attention in the long run. The only people ever harmed by dislikes are corporations trying to advertise a product or msm outlets who are trying to worm their way into Youtube to escape their dying cable platforms after talking down to Youtubers and Youtube culture in general for many years prior.
The only way IMO for ratings to serve an actual purpose on Youtube is to tie it to comments by allowing people who post a comment to rate a video from 1 to 5 stars and have said rating appear next to their comment. Only allow people to rate if they've watched a significant portion of the video (Youtube already tracks watchtime so this shouldn't be hard at all to implement) to avoid people blindly rating a video without even watching it.
This way you no longer have videos that get 10K likes in the first 5 minutes with 50 or so random dislikes, in which nobody will ever have any idea why they were left in the first place, meaning the creator gets absolutely no feedback whatsoever, which is the entire point of a rating system to begin with.
