How could people dismiss real world data that you didn't share? You only shared your interpretation of it and people pointed to lots of ways that this interpretation could be wrong. What data is this? Did you conduct a survey asking people if they “want” a dislike button? Or did you just measure usage frequency of the dislike button and decided that people didn't want it because it wasn't used as frequently as the like button? How could low usage frequency mean users don't “want” it?
