The court order was not misunderstood, it was executed exactly as written. The person(s) who made the final verdict are the ones that misunderstand the technology and that's not the ISPs fault.
The judge's directions were overly-specific but I think his intention was quite clear. If you're arrested and put in badly-designed handcuffs that you can open with no effort, I don't recommend taking them off, regardless.
Historical lesson: I had just joined Microsoft in 1996 when it interpreted a court order literally, using this same attitude, and released a version of Windows without any Internet Explorer DLLs, which was of course not functional. Despite this being exactly what he'd ordered, the judge interpreted this as the corporate equivalent of a toddler having a tantrum, and things went (way) downhill from there.
