Creators can view their like and dislike percentage, and around when the extension came about, many large youtubers were able to confirm the accuracy of the guesstimate that the extension gives you (on new content after the dislike indicator was removed). There are enough users and historical data to make the calculations reeeeally close.
It isn’t a real count of users who have clicked the dislike button, YouTube no longer makes that data available.
So I would not put much stock in that number.
I’m well aware of how it works.
Then why put any stock in it whatsoever
