Putin won’t use nuclear weapons and he can’t realistically escalate the war.
That’s a huge bet to make. The whole point of nuclear deterrence is so nuclear powers don’t think to directly engage each other in any serious way. No one is anxious to call a nuclear bluff, especially since this is basically win or die for Putin.
Did people call RCS open source? I’m not a huge follower of the standard, but I don’t think I ever heard that said. In fact, I’ve heard people complain about not just the proprietary encryption but lack of E2E and carrier/Google control.
Its only advantages are that it is better than SMS and supported by the carriers, Google and Apple sometime this year.
It’s a shitty standard but given how shitty SMS is, I’m willing to hold my nose and jump in.
