I find the autoplay so annoying because it hides the thumbnail which was carefully designed to communicate why I should click on the video and replaces it with, usually, a talking head or stock footage. Often the video gets inexplicably added to my watch history, and if I do choose to click on it I have to go back to the beginning because I missed the start of the audio
Additionally there's a bug on the Android app that it sometimes doesn't show video titles (or the worlds worst A/B test?), so scrolling through I just see talking heads (since it autoplays instead of showing the video thumb) and have to force restart it to actually understand what's going on.
They're making slot machines, effectively.
