Does this mean that freebsd, netbsd, maczfs, zfs fuse driver for linux and the tons of other projects are all at risk? Till today, nobody of them has been sued. Don't they work on the 28th release of zfs, the last one considered free before it became closed source? Did closing the source "edit" the conditions of previous releases?
