Thanks for clarifying your claim.
Without having read all the stuff, and in fact mostly just having read the first few pages of the judgement that you posted, I think it's clear that a key part of (B) is that the ISP argued that the gag was unconstitutional. I have seen no evidence so far saying that the judgement against the FBI gets the ISP off the hook for turning over the data.
I agree that, insofar as (B) was about not turning over information, (C) seems reasonable.
I also agree that, as these things go, every time the "bad news" involves "was taken to court", we should remember that the news could be worse, involving arrest or ruin. So yay there. Then again, taking people to court often results in arrest and ruin, so it's kinda a partial victory. But still, yay for rule of law.
There's a place I disagree with you, though:
D, if true, horrifies me. "You're not only allowed to disobey, you're not allowed to ask the court for permission to disobey. Making use of the judiciary is a crime." That's a horrifying assertion to make.
D also, based on the account given, seems insane. The courts had already actively stated, in 2005, that both your version of (B) and my version of (B) are legal. As I write these sentences, I remind myself that any time someone else seems insane, odds are good that I don't have the whole picture.
