There are a number of words and phrases that we recommend avoiding, or avoiding in certain contexts and usages.
Some are ambiguous or misleading; others presuppose a viewpoint that we disagree with, and we hope you disagree with it too.
For instance, we avoid describing nonfree software as “closed.” We call it “nonfree” or “proprietary”.
The expression “BSD-style license” leads to confusion because it lumps together licenses that have important differences.
In effect, it assumes that free software ought to coexist with software that does not respect users' freedom.
We believe that distribution as free software is the only ethical way to make software available for others to use.
For instance, freedom 2 says that that user is free to make another copy and give or sell it to you.
But no user is to demand a copy of that program from any user.
