Z:gnu-www-ja-words-to-avoid--7e16a5-Describing nonfree software as/en

Describing nonfree software as &ldquo;closed&rdquo; clearly refers to the term &ldquo;open source.&rdquo; In the free software movement,  we do not want to be confused with the open source camp, so we are careful to avoid saying things that would encourage people to lump us in with them. For instance, we avoid describing nonfree software as &ldquo;closed.&rdquo; We call it &ldquo;nonfree&rdquo; or  &ldquo;proprietary&rdquo;.
