When software is free/libre, the users control what it does. A non-free or proprietary program is under the control of its developer, and functions as an instrument to give the developer control over the users. It may be convenient, or it may not, but in either case it imposes on its users a social system that keeps them divided and helpless. Avoiding this injustice and giving users control over their computing requires the four freedoms. Freedoms 0 and 1 give you control over your own computing, and freedom 3 enables users to work together to jointly control their computing, while freedom 2 means users are not kept divided.17
