-different movements which differ in their basic philosophy. The Free
-Software Movement is idealistic, and raises issues of freedom, ethics,

-founded in 1998, studiously avoids such questions. For more explanation,

+idealistic, and raises issues of freedom, ethics, principle and what
+makes for a good society. The term open source, initiated in 1998, is
+associated with a philosophy which studiously avoids such questions.
