Some free software developers prefer noncopyleft distribution. Noncopyleft licenses such as the XFree86 and BSD licenses are based on the idea of never saying no to anyone&mdash;not even to someone who seeks to use your work as the basis for restricting other people. Noncopyleft licensing does nothing wrong, but it misses the opportunity to actively protect our freedom to change and redistribute software. For that, we need copyleft.
