and zfs is not under satan license, firstly because that doesn't exist, secondly because it's cddl actually.
do you know that cddl is basically an mpl-respin? then firefox is "satan licensed" as well?
and don't blame oracle/sun or anything else for GPL being so incompatible with pretty much anything (it's barely compatible even with itself in earlier incarnations).
and also don't have the incorrect feeling of btrfs being owned by the community any more than zfs is. why would that be the case? you may obtain the source code (just like for zfs), but you in no way will own any IP. you really lack points, you just say random bullshit
