That's a stupid reason. He's not dead (or at least imprisoned) yet because USA doesn't have an extradition treaty with Russia. What does a chat app have to do with it?

If the US government wanted to send a hit squad to Russia to take him out, the fact that he uses Signal instead of WhatsApp isn't what would be holding them back.

You can read into it however you want, but the fact is that USA isn't going to essentially invade Russia over him.
