Recently, whenever I search at YouTube, query suggestions pop up. At first I had the option to turn search suggestions off, but later on they are automatically enabled with absolutely no way of disabling them. Parent company Google has that option of disabling search suggestions, but only on its own website. YouTube is different. Some users there want to search videos their own way; when they see the suggestions box, sometimes they get distracted.
YouTube users are NOT morons. They have their own way of searching videos. Search suggestions should not be mandatory!
