According to the first draft of GPL 3.0, published last week, the software it covers will "neither be subject to, nor subject other works to, digital restrictions from which escape is forbidden".
The license adds: "DRM is fundamentally incompatible with the purpose of the GPL, which is to protect users' freedom."
But Torvalds says it is "insane" to require people to make their private signing keys available. Such keys are typically used by individuals to generate a digital signature, or to decrypt messages and files. The creator of Linux won't make his own keys available.
"I don't think the GPL v3 conversation is going to happen for the kernel, since I personally don't want to convert any of my code," he says.
