Well, he says

So presumably the licensing problem mentioned by your parent's comment is weighing heavily here. I think this "don't use ZFS" statement is most accurately targeted at distro maintainers. Anyone not actually redistributing Linux and ZFS in a way that would (maybe) violate the GPL is not at any risk. That means even large enterprises can get away with using ZoL.
