Just to add to it, torrent isn't piracy technology, it is just a sharing protocol. Netflix could very well leverage that to lighten distribution load. Didn't think of that, nice catch.

Im pretty sure that would be illegal, but even if not there would be such pushback at using customers own bandwidth to distribute their own content.

World of Warcraft was distributing updates as torrents 20 years ago. It was fine.

Netflix for instance running their own tracker, then clearly advertising an advanced tier with lower pricing, with good documentation on how to set up, is just enough

It's actually pretty wasteful that it doesn't work that way.

You cant simply start using your customers bandwidth to distribute your own content.

Who said Netflix was offering the torrent?

just throw it in the TOS >:^)
