Re: [Trisquel-users] Canonical merges GPL-incompatible kernel module ZFS to the kernel tree for Ubuntu 16.04

"Equivalent exceptions have existed for many years, for various other stand  
alone, self-contained, non-GPL and even proprietary (hi, nvidia.ko) kernel  
modules."

The GPL contains no such exception. Their entire argument is that, since  
other GPL violations are going on (proprietary kernel modules are often GPL  
violations) that adding one more with ZFS is okay.
