Stop damning the GPLv2 no derrivatives. Given the main author, the project leads and the supporting developers and steakholders on the Linux kernel project have defined what they expect the phrase "derrived work" to mean already in extreme detail given past court cases it's closest that is and isn't expected to be allowed the lisence and its scope is now a resolved issue. Unless you plan to prosecute this in a territory in bad faith.

The ZFS situation here is a completely different (as is past bad behaviour by Nvidia/VMware) kettle of fish and doesn't need to be dragged into via a license discussion on an ABI thread.

The kernel keeps an evolving ABI as expected. This is a win pro/con for Linux, but frankly its so rare to hit an incompatability at the kernel layer it's as good as stable. More things break elsewhere typically many times before this is an issue on MacOS or Win1x for that matter...

As for anticheat what's that even got to do with Linux' API situation is beyond me.
