BS. The document you link to indicates quite clearly that they had no intention of making it anything less than "top secret" after it was found unconstitutional:
>in response to the unauthorized disclosure of classified information, the government has declassified certain information concerning intelligence collection pursuant to Section 702
>[the government] further provides notice [...] that it has
determined it will release to Plaintiff a redacted version of the [FISC] opinion previously withheld [but requests a delay]
It's only because the EFF requested it (after Snowden's disclosures) and fought for it in court that the finding of unconstitutionality will now be made public. Or rather, whatever parts the government decides to let go of.
Yes, all of the FISA rulings are secret by default, but redacting a ruling to remove classified information is not the same as fighting a FOIA request.

Don't let my facts interrupt your rant, though.
