Every day we, as well as general consumers, pay money for someone to run something for us because we don't care to run it. I can run a mail server. But please, please please, take my money to do it. I like to sleep, I like my mail to work, and I like to work on more exciting projects.

Bittorrent should open the code with a license that permits them to run a service they can charge for, but anyone else can use for free.
