I've been able to deal with most of the enshitification of Youtube, but now playback speed controls are no longer available in some of my Youtube playbacks. Refreshing the page sometimes makes them available. And there's a button to enable them by subscribing to Youtube Premium.
I'm going to write to the channels that I subscribe to, to let them know why I'm leaving Youtube. Time to settle on an alternative service.
The biggest issue with going to an alternative is that one doesn’t really exist. Yes, there are other video sharing sites, but they have a tiny sliver of the content YouTube has, as a viewer. As a creator, they have only a tiny sliver of the viewers, which hurts monetization efforts.
