The SFC can get stuffed. Their argument says nothing in particular about ZFS and is essentially "the kernel is GPL and therefore ALL modules MUST BE GPL.

Their stance isn't just rejected by nvidia and company, but also by the kernel devs most notably torvalds himself.

Torvalds himself has personally refuted the "linking inescapably means you're derived" point on multiple occasions, and yet here they are continuing to wave it around because that's how they wish it worked.
