The Kororaa project just issued a final statement about the GPL issue which arose earlier this year. "At this stage I have decided to take the opinion that non-GPL modules are violations of the Linux kernel and are also unethical. This means we will not build non-GPL drivers against the kernel and as such Kororaa will not be shipping non-GPL modules in any future products. Of course if the end user believes non-GPL drivers are acceptable, then he/she is free to install them on their own system. For myself however, I am using the Linux kernel to create a product. If it was not for Linux then it would not exist and I therefore have a responsibility to respect the license of the kernel."
