Richard Stallman said on October 01 2008, that Moonlight is Free Software in an interview where he was asked a leading question meant to bash Moonlight by someone who is widely known to criticize Moonlight and everything else Novell does:
 "Q: Microsoft encourages developers to build Web sites that incorporate Silverlight. For GNU/Linux to be able view Silverlight objects, Moonlight, which is built on top of Mono, needs to be downloaded from Novell’s Web site. Would you advise GNU/Linux users to install Moonlight and accept such changes in the World Wide Web?"
 "RMS: Moonlight is free software, so I don’t see anything bad about installing Moonlight as such. It seems that the reason it needs to be downloaded from Novell’s web site is that it isn’t ready to be included in any GNU/Linux distros."
 Seems to me that unless you think you know better than Richard Stallman, Moonlight [i]is[/i] Free Software. Period. End of discussion.
