So I guess this means GFW is still alive

It was on a month-long hiatus. Everything on their website says "October" for the last event. Even looking up match results says "October".

So them having a match (if they even did) in a super-dark format (so dark, that it wasn't broadcasted or even in front of fans) doesn't count as them being alive.

This is just their way of trying to stay relevant by going "Look guys, Cody Rhodes".

Even if it's alive, it's going to the grave with Cody Rhodes as champ.
