Yet another original meme by Lemmy.

The world needs him more than ever today. RIP 😢

Its a separate platform. It could be used to cache YT videos but that’s not its primary purpose.

Also its a separate okatform. Could be used to cache YT videos but that’s not its primary purpose.

Partially correct. You can self host peertube instances. What differentiates it from YouTube is:

• Instances can share their video lists with other instances via ActivityPub. Even to Mastodon and Lemmy.
• PeerTube video player is peer to peer. You can download the video from the server directly or from another peer watching the same video. This may be helpful for livestreams.

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.
