Sounds like a torrent
Because it is torrenting. I clicked on the “More information” link in the popup and:
PeerTube uses the BitTorrent protocol to share bandwidth between users by default to help lower the load on the server. The main threat to your privacy induced by BitTorrent lies in your IP address being stored in the instance’s BitTorrent tracker as long as you download or watch the video.
No idea about copyright though, but I also don’t quite understand the issue there that doesn’t apply to ActivityPub itself too.
Why are people saying this was Reddit’s april fools? It clearly says it’s made by /r/gamesonreddit, not the admins.
