Richard Stallman Program Quotations

If programmers deserve to be rewarded for creating innovative programs, by the same token they deserve to be punished if they restrict the use of these programs.

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.

If you use a proprietary program or somebody else's web server, you're defenceless. You're putty in the hands of whoever developed that software.

designed to prohibit all free software. It covers only code that implements, precisely, the Microsoft formats, which means that a program under this license does not permit modification.
