Stallman needs to join the real world
Stallman needs to get a grip on reality. He has been out of touch for so long that he's become a joke. Personally I think that the GPL is the worst software license ever written. I'm all in favor of open-source, but GPL is viral-source.
But I diverge. Let's examine the C#/Mono situation for a moment shall we?
Ever heard of this little project called Silverlight Stallman? MS is putting a lot of horses on that wagon. And do you know how they are supporting the *nix community? By putting their full stamp of approval and backing on the Moonlight project. Do you know what the heart of Moonlight is? Yup, Mono and C#. If MS decided to pull the plug on Mono/C# they would be cutting their own throat. That is not going to happen.
Stallman, you need to realize that the culture at MS is changing, and support for open source is part of that change. By posting this nonsense you just egg MS on to do the wrong thing and pull the plug. Don't be an idiot!
