As I said, they’re related. That is All Writs Act is a United States federal statute, codified at 28 U.S.C. § 1651, which authorizes the United States federal courts to issue all writs necessary or appropriate in aid of their respective jurisdictions and agreeable to the usages and principles of law. A writ is a form of written command in the name of a court or other legal authority to act, or abstain from acting, in some way. Also my understanding that the National Security Letters vendors can simply reissue them automatically to maintain persistent data feeds. Disclosing actions taken via All Writs Act to enable national security letters would likely be a disclosure of them similar to warrant canary.
