If the program gives you these four freedoms then it's free software, which means the social system of its distribution and use is an ethical system, one which respects the user's freedom and the social solidarity of the user's community. But if one of these freedoms is missing or insufficient, then it's proprietary software, nonfree software, user-subjugating software. It's unethical. It's not a contribution to society, it's a power grab. This unethical practice should not exist; the goal of the free software movement is to put an end to it. All software should be free, so that all users can be free.
