Huh yea you've actually got a great point there. Also one of the YouTubers I watch is quite open about his knowledge on content creation and the algorithm and he once claimed yt knows when and to whom showing ads is beneficial, if you don't mind sitting thru ads your supposedly more prone to get them, which is the reason why every time I'm using the official YouTube client for whatever reason I make sure to close and reopen the video as many times as it takes until I get it to start playing with no ads 😂 If that is true they'd def use that as an opportunity to roll out more ads cus no ones there to skip em
