It's hardly an ordeal to press ctrl-shift-n, or right-click and "Open link in incognito window". There are no ads with uBlock Origin allowed in incognito windows. There is no need to worry about manually maintaining watch history either.
Fair point, but I'm already paying for YT Premium and on mobile switching to an Incognito tab would be a lot more work. I tend to watch a lot more YT content on mobile like during my commute on the ferry. On desktop definitely agree though!
