Their sources aren't very good or quite outdated... No idea about the root of this scandal with licenses but surely this is not affecting Russian Government VIP fleet. Pilots with allegedly fake licenses are flying in LED-based Rossya Airlines. However Rossya Airlines is not the same as Special Flight Unit "Rossya" which operates Russian Government fleet.
However it is easily traceable why this confusion happened - since early 90s RusGov fleet was operated by Unit 235, which was then renamed to State Transport Company Rossya, which then merged with LED-based Pulkovo Airlines under name "Rossya", and after some years VIP unit was separated again into Special Flight Unit "Rossya" while commercial fleet remained "Rossya Airlines" and was merged with Aeroflot.
