Until we see alternative OSes based on alternative licenses take a bigger spot than LInux, the GPL is in no danger.
It's always annoyed me when people have spoken about the GPL as if it's a living, breathing, entity. It is a license and nothing more, not a culture, nor a way of life.
Unless the GPL is found to not be legally binding, the GPL as a license will never be in danger of anything.
NOTE: Please don't take this as a personal attack. Had I mod points I'd mod you insightful for everything else you had to say.
I consider a new device or technology to have been culturally accepted when it has been used to commit a murder. -- M. Gallaher
