Free software is about freedom (liberty) for the end user. It's not about control by the author (except in specific limited respects). If you want control by the author, then you have a different philosophy. Freedom is about giving up control. More freedom, less control. More control, less freedom. Get it?
Then why isn't it just public domain software? I don't see what's so bad about having contributors agree to share with the author if they share with anyone else. That doesn't seem like 'control' to me. -- license-discuss archive is at http://crynwr.com/cgi-bin/ezmlm-cgi?3
