Z:gnu-www-ja-free-software-even-more-important--8e7a49-When you use proprietary progr/en

When you use proprietary programs or SaaSS, first of all you do wrong to yourself, because it gives some entity unjust power over you. For your own sake, you should escape. It also wrongs others if you make a promise not to share. It is evil to keep such a promise, and a lesser evil to break it; to be truly upright, you should not make the promise at all.
