Anybody who thinks Free Software is anti-copyright or disrespectful of intellectual property should take a look at Mark Jaquith’s post, What a GPL’d Movable Type means. Let’s be clear, Anil Dash takes issue with Jaquith’s interpretation, but the point is Jaquith’s offense at what appears to be Six Apart’s grabbiness for any code somebody might contribute.
Freedom 0 was one thing, the willingness of a person to pour his or her sweat into something, then watch somebody else (or even risk watching somebody else) profit from it is another.
