Non-free software carries with it an antisocial system that prohibits cooperation and community. You are typically unable to see the source code; you cannot tell what nasty tricks, or what foolish bugs, it might contain. If you don't like it, you are helpless to change it. Worst of all, you are forbidden to share it with anyone else. To prohibit sharing software is to cut the bonds of society.
