If I understand it correctly, as a PeerTube viewer I'm not only downloading the video, but also sharing it. Before I watched it.
This is a problem in countries where uploading copyrighted and illegal material has strong legal consequences (so I'd not want to share a video before I watched it fully so I can at least can see it doesn't have any obvious illegal content)
