Is the blog displayed on your domain or theirs? To what extent do they moderate content you have on the blog? Do they promote your blog to other users of WordPress?
I feel like if the answers to those questions change the outcome, then the problem is more nuanced than a single line quote followed by "that's just insane". Especially since I think it's more than possible to come up with a list of questions that justify the court's decision.
(Probably something like "does the news org initiate the discussion, do they have the ability to moderate the discussion, does their branding appear prominently on the page").
