Z:gnu-www-ja-categories--11765c-Proprietary software is anothe/en

Proprietary software is another name for nonfree software. In the past we subdivided nonfree software into &ldquo;semifree software&rdquo;, which could be modified and redistributed noncommercially, and &ldquo; proprietary software&rdquo;, which could not be. But we have dropped that distinction and now use &ldquo;proprietary software&rdquo; as synonymous with nonfree software.
