Back in September of 2005 I wrote an entry on Microsoft's confused and self-destructive position regarding Mono, the open-source implementation of a .NET runtime/C# compiler. It is great to see that Microsoft has cleared the air, likely in reply to some recent comments by Richard Stallman.
However you feel about Stallman, he should be thanked for eliciting this position declaration and finally helping to legitimize Mono. .NET / C# developers should rejoice at this development.
