At least, you know that part.
Except, it's not accurate.
I would simplify it in English like this: there's a lot of *clans* in Russia and various oligarchs align themselves accordingly and yes, there was some falling out for some but Putin exiled a few for appearances and hey, with competing clans, sometimes one group decides to cut ties or edge you out. There's still a ton of oligarchs in Russia and many have a lot of influence and power. $$$$$?!? Obviously, some are very good at being accomodating and cooperative. Anyway, I don't anticipate too many receptive replies but imho, many of the replies were not too accurate if not very specific.
