While I mostly agree with this, it's inaccurate to say that Open Source Software is more liberal than Free Software. The issue of copyleft vs. permissive licenses is orthogonal to that classification. The difference between Free Software and Open Source is mostly that of intent: Free Software is primarily political, with Freedom being the ultimate goal, while Open Source is primarily practical, with high quality software being the ultimate goal. In practice, almost all software that meets the definition of one meets the definition of the other.
