YouTube removing the dislike count destroyed that site's usefulness for reviews. Now there's no good way to tell the algorithmically created videos from genuine reviews without watching them, which then inflates the generated crap videos higher. Big channels can still do product reviews but reviews from average people are now unfindable under a sea of generated sewage content. Since big channels often are sponsored (and not always disclosed regardless of YouTube policy) and have a very narrow range of products they review, a huge chunk of functionality died the day YouTube decided to protect the feelings of political campaign staffers while tossing an enormous amount of content completely unrelated to US political ideological struggles into the void.
