The influence of the "dislike" button could be limited by Youtube. The goal of this initiative is to fight against the "haters" who maliciously hate videos in order to reduce their reach.
This was announced last January 29 in a video, by one of the directors of projects management, named Tom Leung, on the channel "Creator Insider" platform. He detailed the options discussed internally.
YouTube is thinking about several solutions. The first would be to be able hide the number of likes and dislikes of a video. This would not prevent users from clicking on the thumbs, but no one, apart from the videographer, could tell how many liked and how many did not like the content.
The second solution, is to set up a small window that would display when dislike a video. Users would be asked why they put a thumbs down: is it because they do not like the channel in general, was not the information in the video sufficient? Such a system already exists on YouTube. When you want to no longer see content in the list of content suggested by the platform, you must select a reason from a few proposals.
All of these options have so far been only "slightly discussed" and Tom Leung insists that if none is satisfactory, the system in place will remain so until a better idea.
