YouTube will hide public dislike counts on videos, only the creator will still be able to see how many dislikes they got.
Following a test in March, the company says the change is to keep smaller creators from being targeted by dislike attacks or harassment, and to promote "respectful interactions between viewers and creators". The dislike button will still be there, but it'll be for private feedback, rather than public shaming. The good thing about the dislike counts was that it couldn't be deleted, now companies can just delete negative comments and there will be no public metric to rely on. Link
