[Trisquel-users] Re : .NET Core is open source

[lcerf]

The reason for the core to be permissively licensed is to keep having  
proprietary software around. Like additional libraries that (potentially free  
software) applications will use (making them impossible to run in freedom). I  
see nothing positive in that.

And the GPL often is a good choice for libraries:
