I haven't followed the ZFS stuff much at all, but SFC's news post about it the other day did make me wonder why they were doing it. I think it's important to enforce the GPL and other copy-left licenses when they are being blatantly violated, even if the original authors no longer care about the project. But if it's an unintentional license incompatibility, where the spirit of the licenses are roughly aligned, who really cares? Who is benefiting by bothering Canonical or the ZFS-on-Linux developers with these license concerns?
In my case, SFC is pro-bono council for the Wine project, from which I derive my income. So even if I don't always completely understand what they do, I feel I should pitch in because they contribute to my livelihood. I'm not a legal guy, I don't pay super close attention to this stuff, I trust them to do something not far from "the right thing."
It might help if you wrote to them telling them how you feel. I will not think badly of you whatever you decide to do going forward. I realize that this is an awkward situation and if I were you, I would probably have made the same decisions.
The unfortunate situation aside, thank you for your work on Wine. Wine has been helpful to me on multiple occasions. :)
