The algorithm is designed to keep you on the platform with endless feeds of content you might click on. And the site is designed to force you towards the algorithm as much as possible. They don’t want to give you choice about how you might want to view content, they just want you to stay on the platform.
Personally I like just putting all the new content from my subscription that I am interested in, in a watch list then playing through that list and leave when I am done. But youtube is making that workflow harder and harder. Just recently they moved the add to watch later button from the hover on the video to a submenu, resulting in a lot more clicks to do what I used to. And it is now very hard to actually manage your subscriptions in bulk.
