But if it were that simple, couldn’t a provider have a page (say /canary/<user>.txt) that makes a similar attestation on a per user minute by minute basis, thus directly disclosing not just that there was a warrant, but for who? If the legal basis is protection against compelled speech, then logically that should be “ok” as the government “can’t” compel you to update it. I realize this is question is bordering on reductio ad absurdum, but not intentionally.
