Let me set a scene for you. You have a leaking pipe, and go to YouTube to find a tutorial video on how to fix it. You find 100 videos that may help. You click on the first video, and notice there are 350 likes, and 2,000 dislikes. You decide to go to the comment section, and notice lots of people complaining that the tutorial did not help. You decide that this is a bad video, and go on to the next.
Now imagine this, you see a video with 350 likes, the dislikes are hidden. You would think this is a good video. There is nothing telling you that this is a bad video, so you don’t go to the comment section. A month later, you are left with a wet basement!
Now you can probably see why the dislike count is so important. Sure, every once and a while this can protect a creator from a dislike spamming, but taking it away causes bigger problems. And let’s be honest, YouTube didn’t really do this to protect creators, they did it for the brands.
