I find it worrying. Even if Russia is in the wrong here, I do see an RT ban in particular as a dangerous move. Even in wartime I do think it's important to be willing to listen to the other side. They may be wrong about the big picture, but there could still be an interesting tidbit or two to takeaway. All this talk made be go check RT out and one thing I learned is that the flight ban has left Russian tourists stranded. Allowing them safe passage home does not seem unreasonable.

I also see it as turning up the tension in a way that may be hard to dial back down later. When you are cutting your self of from information, you are also cutting yourself of from the information that lets you reevaluate that decision.
