I find it interesting that the SFConservancy argues 'Oracle has a magic wand to make this all go away' by re-licensing ZFS but completely ignores that just as much they could re-license the kernel under a CDDL compatible license. Given that Linux (in the broader sense) is asking for something it'd sound more reasonable for them to accomodate the other parties demands.
What they do is like saying "Hey I want to buy your house, what you don't want to sell it? How about you make it cheaper then so I can afford it!"
