Yes. But even if Btrfs doesn't die, Btrfs and its GPL licence puts other *nix systems in exactly the same position as ZFS is on Linux: they can use it, but they can't distribute it with their kernel. This isn't any better for interoperability.



What stops them from releasing ZFS under the BSD license? GPL is there for good reasons and it's the best license when you want to compete with other projects. However, its restrictions have nothing to this thread and strange Oracle's behavior.
One of the disadvantages of the BSD license to users, is that it doesn't grant you a patent licence on the code, like eg. ZFS's CDDL does.
