For YouTube, a number of reasons: 1) The recommendation algorithm provides entirely negative value for my use case: 1a) I have a very small set of videos I regularly enjoy watching, from a select group of channels. Recommendations tend to direct towards videos I have no interest in at best, or, more frequently, are actively irritating. 1b) In the rare case the algorithm happens on a video I might enjoy, it is almost always something I have already watched. I don't know if it entirely fails to take view history into account while recommending or if it's simply a matter of my small target interests, but either way, I do not remember the last time I intentionally followed a recommendation. 2) I often leave a video on either in the background or on a second monitor. When enabled, YouTube autoplays regardless of if the window is focused, meaning the obnoxious recommendations break my workflow by forcing me to locate and stop the video. 3) YouTube fails to normalize audio. Therefore videos autoplayed after a quiet video have the tendency to blast out my eardrums. I also find autoplay a rather exploitative way of increasing viewer retention in general - it abuses the psyche and addictive nature of the internet for the sake of profits.
