If the licenses are incompatible, then you cannot ship them together. Calling that FUD is a bit rich! Try going through the process at Fedora. The legal team will stop you. Licenses allow you to distribute things despite copyright. Usually distributing software without a license is illegal, though there are exceptions in some countries for music and movies. You can obviously nitpick about that he uses "illegal". However, the discussion was about why ZFS is not distributed. That is what the answer was about, incompatible licenses making it (somewhat) impossible for distributions to carry it. Now various distributions do have e.g. "nonfree" repositories, but incompatible licenses are a big problem. Responding to such concerns with "just spreading FUD" seems to (hopefully) indicate you're not involved with any distribution.
