No need to &quot;Arrgh.&quot;.  I&#x27;m asking serious questions that seem relevant, in which I&#x27;m interesting in getting actual opinions.<p><i>And if they don&#x27;t consent and Oracle does, surely the community can duplicate the effort quickly.</i><p><i>it&#x27;s possible that all OpenZFS copyright is already assigned to Oracle -- I have no particular knowledge</i><p>As a reference, the AUTHORS[0] file from the &#x27;zfs on linux&#x27; project that was imported into ubuntu lists 73 authors not including the Oracle developers, which appear to be both individuals (gmail accounts, etc) and multiple individual businesses (nexenta, ovh, etc)<p>This still seems to fall in to the category of &quot;It&#x27;s must be easy for you, because I could totally do it in 2 hours&quot; that developers (such as myself) sometimes fall into where a task is deemed &#x27;easy&#x27; because the complexity is hidden.  It really seems like neither could easily relicense, so there is no magic wand.<p>[0] - <a href="http:&#x2F;&#x2F;kernel.ubuntu.com&#x2F;git&#x2F;ubuntu&#x2F;ubuntu-xenial.git&#x2F;diff&#x2F;zfs&#x2F;AUTHORS?id=b65ce14d3445e8fe69b5d59aaaf2699319714179" rel="nofollow">http:&#x2F;&#x2F;kernel.ubuntu.com&#x2F;git&#x2F;ubuntu&#x2F;ubuntu-xenial.git&#x2F;diff&#x2F;z...</a>
