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.

The paradigm of competition is a race: by rewarding the winner, we encourage everyone to run faster. When capitalism really works this way, it does a good job; but its defenders are wrong in assuming it always works this way.

It's clear that other problems such as [...] the domination of business over government, science, thought, and society, are much bigger than non-free software.

Think 'free speech,' not 'free beer.'

If the users don't control the program, the program controls the users. With proprietary software, there is always some entity, the "owner" of the program, that controls the program and through it, exercises power over its users. A nonfree program is a yoke, an instrument of unjust power.

In the free/libre software movement, we develop software that respects users' freedom, so we and you can escape from software that doesn't.

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.
