When you look at those planes on Flight Radar, move your cursor over a plane and click on it. It will tell you info about the flight including it's origin and destination. There are plenty of flights out of Russia to other nations, just not NATO nations. It's a big world folks. Many nations are staying out of this or outright support Russia.
What I read in your posts is that the rest of the world is under a no fly zone for Russian commercial aircraft. That simply isn't so.
But there are still plenty of screws yet to tighten on them.
