Absolutely. Getting ratio'd is one of the few ways users have to express displeasure. They took away video replies, comments are often disabled, but they can't pretend everyone likes their video. At least they couldn't until now. That Verge PC build that would destroy your parts if you followed it? That horrible soulless YouTube Rewind? Logan Paul's "sorry I exploited suicide victims for views" video? Dislikes are a force for good. I can count the videos I've seen unfairly disliked on one hand.
