At least for me, I find Youtube too addictive if it offers me an endless list of vidoes tailored to me. The repulsiveness of the default suggestions means I'm not immediately sucked in.
Youtube is pushing Tik Tok style "shorts" pretty hard. If you ever accidently click on one, the UI makes it very hard to find your way back, and easy just to sit and watch a bunch of 15-second clips.
Even the long-form content is a minefield. The line between educational, informative long-form content (Clickspring, Tech Ingredients, Ox Tools, Matthias Wendel, Alan Millyard, etc) and "lifestyle entertainment" (Matt Armstrong, Cleetus McFarland, Matt's Offroad Recovery, etc) is surprisingly fine (AvE, Tavarish, Rainman Ray, etc), and you might not notice you've crossed it until too late.
Don't even get me started on the videos that contain a vital piece of information that could be written in one paragraph, but spread it over 10 minutes. A lot like the online recipe site disasters.
