I was wondering about all of the original Russian Oligarchs who got fantastically wealthy in the “free market reforms” after the fall of the Soviet Union.

I suppose if you have money, you want power.  And if you have power, you want money.  So conflict was inevitable between the Oligarchs and their rulers.

The Mafia-style economy and government of Russia led to Mafia-style conflicts and, ahem, resolutions.  It seems none of the original Oligarchs are left.  All died in mysterious circumstances.  Some good folks did the work for me and put together a list.  I wonder if Elon Musk and his ilk are fans of history.  I suspect not.
