Perhaps in theory the agreement is still meant to be honoured, but in practice if the agreement was with an organization that no longer exists (0 employees), who would initiate legal action to enforce the NDA? I have no experience in this area, but can't see how the NDA could be enforced by a dead organization.
organization is not a living being. it does not "die" like that, and any damages which it might have to pay, it might reduce by suing NDA violators. why not?
At this stage, sure. But unless MtGox gets revived, what about in 2 years from now? It doesn't seem likely unless the NDA is one of the assets they sell.
by that time i guess nobody would care if the NDA is violated..
