Would they have an incentive to sue - ie. how would that advance software freedom? It seems like all this would achieve is make Linux + ZFS more annoying to use and overall everyone loses. The licenses are incompatible on a technicality, but it doesn't mean there is anything for either side to be gained by suing?
