I like that most of the time, when YouTube interrupts my playlists for no reason, they just say "Video playback interrupted. Continue?" (or something to that effect). Like, it just happened. Maybe they thought I had left my playlist on and gone away, and they were looking out for me!

and then every once in a while, because I totally refuse to get the hint, they hit me over the head with "look, we're doing this because you don't have YouTube Premium, pay us money and we will stop inserting bullshit anti-features into your use of our service". just in case I actually believed it was a feature intended to be helpful and might find a setting to turn it off or something.
