I suspect that it is very "overblown" at this point. Russia are using shit equipment all over. Maybe they're afraid those "thousands of missiles" will land on their heads instead of where they're aiming it because they haven't been maintained for decades.
Russia is using shit, but that shit caused 100s of billions in damage. Yes, Ukraine is pushing them out with more superior weaponry, but the damage Russian “shit” left will be felt for decades.

There have been a few cases of Russian missiles being launched then after 50 metres or so turning round and targeting their own launch site. So you’re not far off
