It still calculates them, and I think it can affect them in the algorithm, but they don't show it because of how common it was for a group of fans or upset users for one reason or another would invade someone's channel and dislike en mass to make the ration of likes to unlikes look bad. It was more accurate to show how many liked a video than all of those that may dislike it as it could include a lot of people that hate that type of content and went into the channel to dislike bomb, or people that didn't even watch the video.
Basically, youtube got tired of their rewinds being utterly shit upon because they are just terrible. But they used other creators who got shit on by their fan base as excuses to remove it. Mostly content that was good for advertising because of being clickbait or similar.
This isn't an explanation, so I can't post it as a top-level comment, so I'm going to borrow yours
> It still calculates them
This is true, and there actually exist extensions for both Firefox and Chrome (and other chromium-based browsers) that return the dislike counters. If anyone reads this and happens to want the dislikes back, go looking for an extension called "return youtube dislikes"

Because it made misinformation or poorly received videos seem better than they are. without a dislike ratio you can't really tell how well it was received by the viewers, only how many positive responses it has, much like other social media platforms.
Government propaganda videos were getting ratio'd into oblivion and this didn't look very nice so they asked their partner Youtube to do something about it and they obliged happily.
