I'm not concerned by his silence.
I'm worried.
Make your own mind up.
Update: Gonzalo Lira was arrested by the Ukrainian SBU and all his electronics were confiscated and instructed to keep quiet about internal affairs so he had no way of reaching the outside world.
He did get some tweets out and they were imo quite ungrateful for the concern expressed for him.
Update: 10.05.22
It seems he can vlog again from Kharkov which suggests to me he's cooperating with the SBU? He hasn't got a choice but he seems to be enjoying his current role.
Update: September, 2023 - Lira was arrested and detained again while trying to make a break for the Hungarian border.
