If I might input my opinion on ratings/likes/reaction buttons, regardless of whatever Kyon seems to be talking about, I like to refer to them as a double-edged sword. On one hand, they promote more constructive conversations about things, by giving people a way to just get their "I dis/agrees" out via button format. This has been a behavior I've seen since my first forum, which adopted a similar system half-way into its existence.
Now here's where the double-edged sword part comes in-- People take likes and dislikes too seriously at times.
The most common complaint against a dislike system is that people will abuse it. This idea also comes with the idea that people will take a "dislike" too seriously.
Now onto what Kyon was saying stuff about, I decided to look on his profile, and saw that he has 24 dislikes. Now lets calculate the percentage of his posts that have dislikes... Almost exactly 1%. Like, I don't quite know, since that's out of 2,355 posts, I think we need to go a bit further to put this in perspective. Kyon has most definitely made more posts since he posted the "I'm done with this forum" bit than he has dislikes. If we take this into account, then we have to consider that most of those aforementioned posts aren't disliked. If someone was actually openly out to get him as of recent, then he should logically have more dislikes than he does now.
But that's impossible, because there's nothing that would logically point towards him being openly disliked. The only thing this could logically be is simple melodrama. Exaggerations of a system that mean nothing in the long run.
Nothing against Kyon, but I just calls 'em like I sees 'em.
