Where 6881 fits
Why 6881 is special
BitTorrent inverts the usual model: the more people downloading a file, the faster it goes, because each of them uploads pieces to the others. It is used for Linux distributions and game patches as much as for anything else.

Technology & computing
In client-server downloading, demand degrades service. BitTorrent makes each downloader a source, so demand improves it. That inversion is why the protocol is used to distribute operating systems and game updates at scale, not only for piracy.
