Now, on the one hand, it’s easy to see the company’s perspective. Smaller content creators on YouTube can get harassed via such targeted dislike campaigns. But on the other, If there really was such a targeted campaign, the number of dislikes not being visible wouldn’t really dampen it since it’s, well, a targeted campaign.
For the average user, the like to dislike ratio is important if you’re actually looking for information. After all, it’s the easiest way to gauge if the video is genuinely helpful. No one wants to spend 10 minutes and one second watching through a video, only to find that the content skirts around the topic in the title without actually addressing it.
