Some people I follow have moved to Odysee[1], seems like a good candidate for helping wean users off YT. There are a handful of YT creators uploading content to both platforms simultaneously. That might be the best way to transition away from YT until the other platforms become popular enough to self-sustain. There's a blockchain under the hood which I'm sure will trigger some HN denizens (I'm a bit skeptical as well) but it seems like a solid concept.
