I understand what happened in the Microsoft case - but it's important not to confuse this with an NSL. In the case of a search warrant, and Microsoft's court maneuvering's everything is done in secret, until it's executed (otherwise the parties could simply take action to avoid the warrant)- at which point everything comes out into the open. In the case of an NSL, when it is served - the person who it's served upon is bound by law not to discuss it, and must keep it secret. Totally different.
