As with all things, it's probably more complicated than that :-)

I personally think that ZFS (from Sun Microsystems) and BTRFS (from
Oracle) were originally convergent solutions to the same problem, much
like Gnome and KDE both try solve the desktop problem. ZFS started out
in the Solaris world, and BTRFS in the Oracle-cloned-Red-Hat world, so
there is that difference.

Then Oracle bought Sun and now Oracle "owns" both codebases, so who
knows what's going in internally at that corporation wrt modern filesystems.

ZFS licensing is a problem that should not exist. AFAIK, Sun owned the
entire codebase and used their own license. Oracle owns it now, so there
doesn't seem to be anything stopping Oracle from releasing the whole
thing under multiple licenses, making the problem go away.
