Durov has indeed left Russia and said it is 'incompatible' with IT business.
Despite what he has already said or might say in the future, this whole conflict is the conflict between the former management (Durov) and the shareholders. No politics in here, just business. I think that Durov was simply 'out of class' here. A rather simple-minded IT nouveau-riche tried to do business with figures like Sechin and Usmanov. The end was rather predictable.
