It has more to do with the targeting algorithm used. Once you start watching some kind of content they start proposing more of the same kind of content to you. So people see less and less contrary ideas. And you can't select an option to "give me quality containt from domains I never touched". Instead of discovering random new content and concept you get pigeonholed into some things you already know and agree with.
