So why didnt Soviets expose the "fake" moon landing?

Hagar asks "BG":

Why is it that your NASA Mafia/cabal, all of our best DoD (aka USAF)
or even
those wise old farts of the
USSR/Russian side can't manage to do
this rather easily?

The hoax zealots' standard answer is that NASA/USSR were in financial
cahoots. They'll say the same for China/India and NASA being all "in
cahoots".
