One thing to remember is that all the internal issues in Russia, be it Gazprom or any other business, are internal to Russia, they have nothing to do with DS. There is plenty of corruption in Russia and almost weekly someone higher up is caught in bad financial dealings. Or rather, they cross a line where someone says, "Enough!". They all steal, during Soviet days it was a way of life for almost all people there trying to survive. Your salary paid for almost nothing. So graft became the way of life and is so ingrained now that I have no idea how many generations have to pass for people to unlearn the behavior. Governments, local or federal, tolerate it up to a point, or rather a missed bribe :-) And then the foot comes down. Its either prison or eating some lead, most choose prison.

One thing that Putin did was replace bribes to mafia to be now directly to police. They call it "donations", of course. If you want your business not to burn, or worse, you pay the cops. That is how bad the graft is there.

Either way, whatever happens there has nothing to do with DS. Have no idea why any news about Gazprom excites anyone here. Especially fake news.
