Which was precisely Sun/Oracle's goal when they released ZFS under the purposefully GPL incompatible CDDL. Sun was hoping to make OpenSolaris the next Linux whilst ensuring that no code from OpenSolaris could be moved back to linux. I can't think of another plausible reason why they would write a new open source license for their open source operating system and making such a license incompatible with the GPL.

Some people argue that Sun (or the Sun engineer) as creator of the license made the CDDL intentionally GPL incompatible.[13] According to Danese Cooper one of the reasons for basing the CDDL on the Mozilla license was that the Mozilla license is GPL-incompatible. Cooper stated, at the 6th annual Debian conference, that the engineers who had written the Solaris kernel requested that the license of OpenSolaris be GPL-incompatible.[18]

    Mozilla was selected partially because it is GPL incompatible. That was part
    of the design when they released OpenSolaris. ... the engineers who wrote Solaris 
    ... had some biases about how it should be released, and you have to respect that.

    And the very next paragraph states:

    > Simon Phipps (Sun's Chief Open Source Officer at the time), who had introduced Cooper as "the one who actually wrote the CDDL",[19] did not immediately comment, but later in the same video, he says, referring back to the license issue, "I actually disagree with Danese to some degree",[20] while describing the strong preference among the engineers who wrote the code for a BSD-like license, which was in conflict with Sun's preference for something copyleft, and that waiting for legal clearance to release some parts of the code under the then unreleased GNU GPL v3 would have taken several years, and would probably also have involved mass resignations from engineers (unhappy with either the delay, the GPL, or both—this is not clear from the video). Later, in September 2006, Phipps rejected Cooper's assertion in even stronger terms.[21]

    So of the available licenses at the time, Engineering wanted BSD and Legal wanted GPLv3, so the compromise was CDDL.

There were genuine reasons for the CDDL - it wasn't an anti-gpl thing. https://www.youtube.com/watch?v=-zRN7XLCRhc&feature=youtu.be...

    Danese Cooper, one of the people at Sun who helped create the CDDL, responded in the comment section of that very video:

    Lovely except it really was decided to explicitly make OpenSolaris incompatible with GPL. That was one of the design points of the CDDL. I was in that room, Bryan and you were not, but I know its fun to re-write history to suit your current politics. I pleaded with Sun to use a BSD family license or the GPL itself and they would consider neither because that would have allowed D-Trace to end up in Linux. You can claim otherwise all you want...this was the truth in 2005.

      This needs to be more widely known. Sun was never as open or innovative as its engineer/advertisers claim, and the revisionism is irksome. I saw what they had copied from earlier competitors like Apollo and then claimed as their own ideas. I saw the protocol fingerprinting their clients used to make non-Sun servers appear slower than they really were. They did some really good things, and they did some really awful things, but to hear proponents talk it was all sunshine and roses except for a few misguided execs. Nope. It was all up and down the organization.

      Yeah, it's hard to understand this without context. Sun saw D-Trace and ZFS as the differentiators of Solaris from Linux, a massive competitive advantage that they simply could not (and would not) relinquish. Opensourcing was a tactical move, they were not going to give away their crown jewels with it.

      The whole open-source steer by SUN was a very disingenous strategy, forced by the changed landscape in order to try and salvage some parvence of relevance. Most people saw right through it, which is why SUN ended up as it did shortly thereafter: broke, acquired, and dismantled.

      And Cooper's boss:
