Depending on your browser, you can look for a “bring back the dislikes” extension. There are usually a few.
Really the only way to make an impact on a video you dislike is to watch as little as possible and do not interact at all. Leave no comment or like/dislike.
Which really sucks, because information like # of dislikes and informative comments are the only real way to determine if the content is worth the time.
I’d also add DeArrow to remove clickbait thumbnails and titles, and Untrap to completely modify nearly everything, such as removing (hiding, really) shorts, like count, view count, comments altogether, even hiding the subscribe button among many other options.
