China and many others run their own CAs, I'd presume Russians could use those if they wanted?

Russians didn't want to use those, until the West made it inevitable.

And why is that?

It's not that hard to find a CA in a more aligned regime.

Rolling your own MITM CA as a replacement just looks like something that was waiting for an excuse.
