Every social platform has a button of " don't like" in our case is downvotes.
Downvotes have many utilities. There are many reasons for a we need to hit a don't like button. I think even if it is something that hits your feelings it could be used the downvote bottom. It is a decentralized chain so in the same way that I can post anything I want, I need to know that if it is something very polemic can also get a downvote. In addition, it can be used as an abuse tool and reward equalization, those are subjective, for example, AI use. Some people don't agree, and it can be used as a bottom.
Being in a social tool like a hive the main source of income is the upvoting button. That should also be hit only when you like the content, and as @achim03 said in his post not even the "upvote" button is used well, so why do people complain about the DV button, it is our nature to complain about getting bad votes, but no one complains about getting unfair votes ( I am telling this but I also never complain about votes that I think that I didn't deserve, hehe)
