Someone emailed me to say that someone that Oracle might be able to change the terms of the CDDL for all software licensed under the CDDL as per sections 4.1 and 4.2. My discussions with lawyers thus far had focused on whether Oracle could change the license for just the OpenZFS code base (the answer is no) without any other copyright holders agreeing. Whether Oracle can change the definition of the CDDL for all software licensed under it (without the statement &quot;version 1.0 only&quot;) is something that I need to run past a lawyer, but that might be possible.
