The dearth of case law here still makes a negative outcome for FSF pretty dangerous, even if they don't appeal it and set precedent in higher courts. It might not be binding but every subsequent case will be able to site it, potentially even in other common law countries that lack case law on the topic.

And then there is the chilling effect. If FSF can't enforce their license, who is going to sue to overturn the precedent? Large companies, publishers, and governments have mostly all done deals with the devil now. Joe Blow random developer is going to get a strip mall lawyer and overturn this? Seems unlikely
