Creators, you'll still be able to see the exact number of likes and dislikes in YouTube Studio. For viewers, if you're in the experiment, you can still like or dislike a video to share feedback with creators and help tune the recommendations you see on YouTube.— YouTube (@YouTube) March 30, 2021
YouTube announced today that they are getting rid of the public dislike count on videos after listening to their content creators. According to them, public dislike counts sometimes motivate targeted campaigns of dislikes on some videos, which can negatively impact the wellbeing of the creators.
