Can you show us where the binary download is located? What makes you say that it's closed-source? The GPL does not (and could not) require that somebody distribute their software to anybody or everybody. A company is permitted to only distribute GPL'ed software to those they choose or to nobody at all. The GPL is only relevant when a company *does* choose to distribute their software to an entity. What that happens, it imposes (to oversimplify) two requirements: (1) They may not prevent that entity from further distributing the software (2) They must make the source code available Do you have any evidence that Cortus is violating either of those provisions?
