I think this may not be enough. The expected behaviour of each other party would be to wait until others sign up so that if the plan succeeds, they could jump out and say they got a NSL too. Since everyone things that way, nobody signs up.<p>I&#x27;m a bit rusty on my game theory, but I do recall there are some ways around this deadlock.<p>One possibility would be if many companies &quot;allowed themselves&quot; to get hacked by a third party (out of USGOV&#x27;s reach) that would conveniently find and publish the documents about NSLs (if such exist). Companies would get the benefit of plausible deniability.
