As I understand it that is a factually inaccurate statement.

You are free to use a DIF/DIX solution which is part of the T10 SCSI
specification and as such an open(ish) standard. That is if you pay a
suitable amount you will get a copy of the standard and are free to
implement it. It is arguably more open than ZFS that has licensing
issues.

Further as I understand it the DIF/DIX solution is actually better than
the ZFS solution on a number of counts, that revolve around it being
baked into the hardware.

JAB.
