Richard Stallman Source Quotations

Proprietary software tends to have malicious features. The point is with a proprietary program, when the users dont have the source code, we can never tell. So you must consider every proprietary program as potential malware.

Proprietary software keeps users divided and helpless. Divided because each user is forbidden to redistribute it to others, and helpless because the users can't change it since they don't have the source code. They can't study what it really does. So the proprietary program is a system of unjust power.

I founded the free software movement, a movement for freedom to cooperate. Open source was a reaction against our idealism. We are still here and the open-source people have not wiped us out.

The GNU GPL was not designed to be "open source".
