I haven't heard them say what format will be included in the torrent, say it's 20 TB blocks of secured archival format. Then you would have to download that full volume ( at least, there are ways to force you to download the full 15 set of 20 TB archives) before decompressing it and see files as is, that would rendering streaming or casual downloading impossible under current tech.

And that's ok.

Anna's archive isn't there to cater to today's wants but to protect what might disappear tomorrow.
