It's kind of like the whole SEO sites that use to plague Google back in the early 2000s. Obviously today they deal with similar SEO nonsense in the form of review sites but at least if you're not looking for a review on a product then you won't usually get them in your first page results. Too bad YT devs don't have that decent of an algorithm for the front page.
It is a disservice to the end-user and to all the amazing creators for whom Youtube is as present an irreplaceable venue for distribution.
