Yeah, the proposal here differs from warrant canaries in that it doesn’t ask people to proactively make statements ahead of time—it just relies on the ability of some people who can speak, to provide evidence that others can’t. So if e.g. Bob and Joe have been released, but Alice hasn’t, then Bob and Joe saying they’ve been released makes Alice’s silence more conspicuous.
