As much as I'd like to see an alternative to YouTube on the fediverse, I can't see myself using it much unless my favorite content creators move on over there too. And I can't see them moving.
I've been tracking the Fediverse loosely since stumbling into StatusNet and OStatus in 2011. To see the fediverse alive and well after being away for so long makes me very happy, though I don't share the same political opinions as many of the people here.
That said, I'd argue there needs to be a way to spin up PeerTube and educate the masses on how to do that instead of starting a YouTube channel.
Oddysee is built on LBRY, which I believe is the closest thing. I think there's something else called PeerTube, but I'm not sure what it is exactly (haven't looked into it).
I might be too pedantic, but Odysee/LBRY is a blockchain-based decentralized network. But its not federated and it doesn't use activitypub like Lemmy and mastodon. I would only call Peertube to be part of the fediverse.
