That's because, despite what the 14 year olds on digg and reddit think, this isn't for you to download on your computer at your house. This is for archival or data-mining purposes.

I apologize for the minor insult at digg/reddit, I just remember a few years ago a link to the archive was posted on digg and everyone started downloading it...unnecessarily wasting wikipedia's limited and donated resources.

If that's a problem, they could have put it up with bittorrent and throttled the bandwidth.

Yeah, this is exactly the sort of problem bittorrent was designed to handle
