They are not the Free Software Foundation!

If anyone is looking for alternative, Deluge is open source and very good (http://deluge-torrent.org/)

While not being open source, BitTorrent Inc. does promote the open standardization of the protocol[1], and employs the creator of bittorrent, Bram Cohen[2], as chief scientist.

μTorrent is, I think, the best suggestion for a client for people who need client suggestions. (having tried a large number of very mediocre competitors, free, open, or otherwise)

I usually stick to rtorrent on the commandline, but that's a shitty suggestion for helping bring awareness to hacker issues.

Personally, I think qbittorrent is a better general suggestion.

I've used both utorrent and qbittorrent and the only difference is the latter does not have any ads bundled.
