How is it a great design for users? Then why even show like count?

Edit: I thought about what you said, and your claim is simply wrong. It still stores the per user reaction, otherwise it won't be able to show me that I've disliked a particular video. There's honestly no good reason to hide the dislike count, other than to please a certain group of users.

Overall, it definitely makes YT a worse site in terms of UX compared to what it was before this change. F for YT
