YouTube can be used in a healthy way: use NewPipe and subscribe to channels with edifying content and then, when a new video appears that you would want to watch properly, send the direct video link to yt-dlp on your computer. You then avoid the actual website, its algorithm, and its enshittification like short-form videos.

Choosing edifying content requires, of course, some caution. Avoid individual “content creators” who might feel pressure to slowly conform their content to the algorithm and sponsors’ demands. Instead, follow e.g. local arts organizations who do their events as part of a whole offline ecosystem, and then just upload video of it to YouTube. Or universities who create teaching content for their own needs but then upload it to YouTube, etc.

Oh sure - or, just realize that 99% of content is absolute garbage and go use your time in something else entirely. It’s what I do - I understand if others choose to do differently with their time and resources.
