Other than him not posting on 2p2 or Discord, which he hasn't done in close to a year now, what evidence is there to suggest that TT was hacked and that the latest update is fraudulent rather than a failed attempt to provide an update for a program that hasn't had an update in about 6 months?
I briefly spoke to him via his Skype account a few days ago. I have no reason to believe that it wasn't him, but I also have no way of proving that it was him.
