You're wrong, and Apple made a mistake: https://arstechnica.com/gadgets/2016/06/zfs-the-other-new-apple-file-system-that-almost-was-until-it-wasnt/ https://arstechnica.com/gadgets/2016/06/zfs-the-other-new-ap... From the article: "Finally, and perhaps most significantly, personal egos and NIH (not invented here) syndrome certainly played a part. I'm told by folks who worked at Apple at the time that certain leads and managers preferred to build their own stuff rather than adopting external technology, even technology that was best of breed. They pitched their own project, an Apple project that would bring modern filesystem technologies to Mac OS X. The design center for ZFS was servers, not laptops—and certainly not phones, tablets, and watches—and the argument was likely that it would be better to start from scratch than adapt ZFS. Combined with the uncertainty above and, I'm told, no shortage of political savvy, the anti-ZFS arguments carried the day. Licensing FUD was thrown into the mix; even today folks at Apple see the ZFS license as nefarious and toxic in some way, whereas the DTrace license works just fine for them. Note that both use the same license with the same grants and same restrictions." It's still not too late for Linux to merge ZFS: https://youtu.be/6F9bscdqRpo?t=5m14s https://youtu.be/6F9bscdqRpo?t=5m14s
