You may not be aware of this, but like everything on PeerTube, the video we are commenting on here is in fact served up via BitTorrent. I got about a third of it from the diode.zone seed, which, if I understand correctly, is paid for out of Micah Scott's Patreon.

The inefficiency of torrents on near-symmetric internet connections is pretty minor. If a 1GiB movie is on Netflix, each user has to download 1GiB of data over your internet connection. If it's in a torrent, each user has to download 1GiB of data and also upload 1GiB of data. The efficiency difference is only a factor of 2. And the 1GiB of upload bandwidth was, in many cases, idle anyway.

(Well, there's also the fact that the users are paying the cost of distributing the movie, rather than Netflix paying part of it. So you'd think that information that benefits the people who receive it, like Linux, porn, and sewing and soapmaking tutorials, rather than the people who produce it, like advertising, would tend to be distributed by torrents. But, for a commercial setup, this is a minor consideration; even ordinary hosted servers pay relatively little for bandwidth, and Netflix probably pays nothing in most cases. I suspect Micah Scott ended up paying about 10% of the cost of me watching this video, not counting the value of my time.)
