The AOC was cancelled!!! So, yes they still have a few days of it still being effective, then that is it....So yes PPRuNe is a good place of information
If somebody wants to buy the company and structure and staff it appropriately I'm quite sure there's a way to negotiate with CAA in order not to reapply for a full AOC issuance. Trade license is much more significant to prove the company is dead.
And no, PPRuNe is not a good place for information but only for few rumors and lots of BS.
