I do know someone did sue them.  Seeing as that person has repeatedly ignored my inquiries as to status after corresponding for several months I think the likelihood is that he won, but agreed to a non disclosure as part of the settlement.

I only say that as I've been involved in these sorts of things before.  It is very common for a party to ask for this if they have reason to want to shut people up going forward.  Considering the way these assholes have tried to control information I have little doubt they would ask for this.

 If there was no settlement, there us no reason to not reply as there wouldn't then be any agreement.

So, I have not been told this directly, however my personal direct experience with other instances in civil/corporate legal battles leads me to think a settlement of some sort was reached.
