I do not mean to discourage people from using those systems, but it is silly to adopt them because a bug got past joint OpenZFS review and landed in the Linux port first. That’s your opinion and while I extremely disagree with it, it is what it is. It might be even true in the case if ZFS on Linux team but on the whole of GNU/Linux, my professional experience is that the amount of bugs and breakage is much higher than on BSD or illumos based operating systems, and to me, quality and stability are the most important things. For me a computer is a tool to make money and so reliability of hardware and especially the software trumps everything else. In fact, apart from reliability and simplicity nothing else is important to me when it comes to software.
