MB, I think you might be confusing mediation/arbitration and suing.
The MKs who accepted a financial settlement through a mediation process DID NOT sue NTM.
Those who filed lawsuits DID NOT accept a settlement through mediation.
As far as I know, the only MKs who have gone through an arbitration process and accepted a financial settlement are Fanda MKs. And I do believe these settlements included a promise not to speak about the settlement or the amount.
Only one lawsuit has been settled so far, and in that one, the MK also received money. Those terms have not been revealed publicly and I do not know if a promise not to talk about the money was a part of the settlement or not.
It remains to be seen if the other two lawsuits will be settled soon or will go all the way to court. Millions of dollars are being requested in the suits, so I am thinking it would be in NTM's best interest to settle before things go all the way to court.
I know this is all complicated and confusing.

I may not have it all straight myself!
